Introduction
1-1 Features
Chapter 1
OMNUC AC Servo Drivers control the power supplied to AC Servomotors with pulse-train input signals and perform precision position control. There are 7 types of AC Servomotors: 30-W, 50-W, 100-W,
200-W, 300-W, 400-W, and 750-W.
H
Motor Output Capacity
AC Servomotors with the following output capacities are available.
S
For 200/230-VAC (170 to 253 V) single-phase, 50/60-Hz Input
30 W, 50 W, 100 W, 200 W, 400 W, and 750 W
S For 100/115-VAC (85 to 127 V) single-phase, 50/60-Hz Input
30 W, 50 W, 100 W, 200 W, and 300 W
The Servomotors also come with and without brakes, and with and without keys on the straight shaft. Servomotors that conform to EC Directives, however, are available only with keys on the shaft.
H
Models Conforming to UL/cUL Standards Available (UL/cUL Markings)
AC Servomotors and Servo Drivers that conform to UL/cUL Standards are now available. Their performance, functionality, and appearance are the same as the conventional U-series (HA/LA) models. They are useful for obtaining approvals required for specific applications.
Models conforming to UL/cUL Standards have the same product names as conventional U-series
(HA/LA) models. As shown in the following table, they are distinguished by the manufacturing date.

H
EC Directives (CE Markings)
AC Servomotors and Servo Drivers that conform to EC low-voltage and EMC directives are now available. These provide the same performance and functions as the rest of the U Series (HA/LA), and will aid in obtaining specifications.
H
Control Functions
Any one of the following 4 control modes can be selected in the parameter settings.
S
Position Control (Factory Setting)
Controls the position and speed of the Servomotor very precisely with pulse-train input signals.
Any one of the following 3 pulse trains can be selected: forward/reverse pulses, feed pulses/ directional signals, or 90
_
differential phase (A/B phases) signals.
S
Position Control with Pulse Stop Input Enabled (HA/LA/V/W Models)
Turning ON the Pulse Stop Input (IPG) prevents the control signals from being read by the Unit during position control.
1-2
Introduction Chapter 1
S
Internal Speed Control Settings
The speed of the motor is controlled with the three speeds (No. 1, No. 2, and No. 3 internal speed settings) set in the parameters. This mode is effective for simple position control or speedswitching operation.
S
Internal Speed Control Setting + Position Control (HA/LA/V/W Models)
Speed control can be performed with the internal speed settings and position control can be performed with pulse-train inputs.
H
Auto-tuning
The gain can be adjusted automatically when the responsiveness has been selected to match the rigidity of the mechanical system. The auto-tuning feature automatically finds the optimum adjustment to match the load, with no need for difficult operations.
H
Monitor
Displays the driver’s operating status on the Parameter Unit.
The following items can be monitored: speed feedback, speed commands, torque commands, number of pulses from the U-phase edge, electrical angle, internal status (bit display), command pulse’s speed, position deviation, and the input pulse counter.
H
Jog Operation
Forward/Reverse motor operation can be controlled from the Parameter Unit. Rotational speed can be set in the parameters.
H
Electronic Gear Function (Position Control)
The number of pulses used to rotate the motor is calculated by multiplying the number of command pulses by the electronic gear ratio. This function is useful in the following kinds of cases.
S
When you want to finely adjust the position and speed of two lines that need to be synchronized
S
When you want to increase the control pulse frequency of a controller with a low pulse frequency
S
When you want to set the movement/pulse to a certain amount, such as 0.01 mm/pulse
The electronic gear ratio is set with parameters G1 and G2 (G1=numerator and G2=denominator).
The setting range for parameters G1 and G2 is 1 to 65,535. The setting range for the gear ratio is
0.01 to 100, i.e., 0.01 ≤ G1/G2 ≤ 100.
H
Encoder Resolution Function
This function allows the encoder signal output from the driver to be set anywhere from 16 to 2,048 pulses/revolution.
H
Software Start Function (Internal Speed Control Settings)
This function causes the motor to be started/stopped in the preset acceleration/deceleration times, allowing a simple position control system to be constructed without a Positioner or Host Controller.
The acceleration and deceleration times are set separately, and the setting range is 0 to 10 s for each.
1-3
Introduction Chapter 1
H
Pulse Smoothing Function (Position Control)
Even high-frequency commands can be executed smoothly by including acceleration/deceleration in the command pulses. The same setting is used for both the acceleration and deceleration times, and the setting range is 0 to 64 ms.
H
Reverse Mode
Forward/Reverse commands can be switched in the parameters, without changing the wiring to the motor or encoder.
H
Brake Interlock Output
Outputs a timing signal interlocked with the motor’s ON/OFF status and rotational speed. The holding brake of a motor with a brake can be operated reliably.
H
Overtravel Sequence
An overtravel sequence compatible with the system can be selected. There are three deceleration methods available: dynamic brake deceleration, free-run deceleration, and emergency-stop torque deceleration (parameter setting).
H
Feed-forward and Bias Functions (Position Control)
These functions reduce the position control time.
S
Feed-forward Function
Reduces the position control time by reducing the number of pulses accumulated in the deviation counter.
S
Bias Function
Reduces the position control time by adding the bias revolutions to the speed control when the deviation counter value exceeds the position completion range.
H
Computer Monitor Software (HA/LA/V/W Models)
The special Servo Driver Communications Software allows parameter setting, speed and current monitoring, I/O monitoring, auto-tuning, and jog operations to be performed from a personal computer. It is also possible to perform multiple-axis communications that set the parameters and monitor the operation of several drivers. Refer to the Computer Monitor Software Instruction Manual
(I513) for OMNUC U-series Servo Drivers for more details.

•
Install Servo Drivers according to the dimensions shown in the following illustration to ensure proper heat dispersion and convection inside the panel. Also install a fan for circulation if Servo Drivers are installed side by side to prevent uneven temperatures from developing inside the panel.
•
Mount the Servo Drivers vertically (so that the model number and writing can be read).

Operating Environment
Be sure that the environment in which Servo Drivers are operated meets the following conditions.
0
°
C to +55
°
C
•
Ambient operating temperature:
•
Ambient operating humidity:
•
Atmosphere:
35% to 85% (RH, with no condensation)
No corrosive gases.
D
Ambient Temperature
•
Servo Drivers should be operated in environments in which there is minimal temperature rise to maintain a high level of reliability.
•
Temperature rise in any Unit installed in a closed space, such as a control box, will cause the ambient temperature to rise inside the entire closed space. Use a fan or a air conditioner to prevent the ambient temperature of the Servo Driver from exceeding 55
°
C.
•
Unit surface temperatures may rise to as much as 30
°
C above the ambient temperature. Use heatresistant materials for wiring, and keep separate any devices or wiring that are sensitive to heat.
•
The service life of a Servo Driver is largely determined by the temperature around the internal electrolytic capacitors. The service life of an electrolytic capacitor is affected by a drop in electrolytic volume and an increase in internal resistance, which can result in overvoltage alarms, malfunctioning due to noise, and damage to individual elements. If a Servo Driver is always operated at the maximum ambient temperature of 55
°
C, then a service life of approximately 50,000 hours can be expected. A drop of 10
°
C in the ambient temperature will double the expected service life.

System Design and Installation Chapter 2
D
Keeping Foreign Objects Out of Units
•
Place a cover over the Units or take other preventative measures to prevent foreign objects, such as drill filings, from getting into the Units during installation. Be sure to remove the cover after installation is complete. If the cover is left on during operation, heat buildup may damage the Units.
•
Take measures during installation and operation to prevent foreign objects such as metal particles, oil, machining oil, dust, or water from getting inside of Servo Drivers.

Impact and Load
•
The Servomotor is resistant to impacts of up to 10 G
{98 m/s
2
}. Do not subject it to heavy impacts or loads during transport, installation, or positioning. In addition, do not hold onto the encoder, cable, or connector areas when transporting it.
•
Always use a pulley remover to remove pulleys, couplings, or other objects from the shaft.
•
Secure cables so that there is no impact or load placed on the cable connector areas.
D
Connecting to Mechanical Systems
•
The axial loads for Servomotors are specified in section 5-2-4. If an axial load greater than that specified is applied to a Servomotor, it will reduce the service life of the motor bearings and may damage the motor shaft. When connecting to a load, use couplings that can sufficiently absorb mechanical eccentricity and variation.
Recommended Coupling
Motor shaft center line
Ball screw center line
Shaft core displacement
Name
Oldham coupling
Maker
Myghty Co., Ltd
•
For spur gears, an extremely large radial load may be applied depending on the gear precision. Use spur gears with a high degree of accuracy (for example, JIS class 2: normal line pitch error of 6
µ m max.
for a pitch circle diameter of 50 mm). If the gear precision is not adequate, allow backlash to ensure that no radial load is placed on the motor shaft.
Backlash
Adjust backlash by adjusting the distance between shafts.
2-17
System Design and Installation Chapter 2
•
Bevel gears will cause a load to be applied in the thrust direction depending on the structural precision, the gear precision, and temperature changes.
Provide appropriate backlash or take other measures to ensure that no thrust load is applied which exceeds specifications.
•
Do not put rubber packing on the flange surface. If the flange is mounted with rubber packing, the motor flange may separate due to the tightening strength.
Make moveable.
Bevel gear
•
When connecting to a V-belt or timing belt, consult the maker for belt selection and tension. A radial load twice the belt tension will be placed on the motor shaft. Do not allow a radial load exceeding specifications to be placed on the motor shaft due to belt tension. If an excessive radial load is applied, the motor shaft may be damaged. Set up the structure so that the radial load can be adjusted. A large radial load may also be applied as a result of belt vibration. Attach a brace and adjust Servo
Driver gain so that belt vibration is minimized.
Pulley
Make adjustable.
Belt Tension Motor shaft Load shaft
D
Water and Drip Resistance
•
The Servomotor does not have a water-proof structure. Except for the connector areas, the protective structure is covered by the following JEM (The Japan Electrical Manufacturers’ Association) standards.
Models Conforming to UL/cUL Standards and Models Not Conforming to Any Standards: IP-42
EC Directive Models: IP-44 (except shaft penetration point)
•
If the Servomotor is used in an environment in which condensation occurs, water may enter inside of the encoder from the end surfaces of cables due to motor temperature changes. Either take measures to ensure that water cannot penetrate in this way, or use water-proof connectors. Even when machinery is not in use, water penetration can be avoided by taking measures, such as keeping the motor in servo-lock status, to minimize temperature changes.
•
If machining oil with surfactants (e.g., coolant fluids) or their spray penetrate inside of the motor, insulation defects or short-circuiting may occur. Take measures to prevent machining oil penetration.
D
Oil Seals
If the motor shaft is exposed to oil or grease, use a Servomotor with oil seals (available as special specification). (Inquire for details.)
2-18
System Design and Installation Chapter 2
D
Other Precautions
•
Do not apply commercial power directly to the Servomotor. The Servomotors run on synchronous
AC and use permanent magnets. Applying 3-phase power will burn out the motor coils.
•
Do not carry or otherwise handle the Servomotor by its cable, otherwise the cable may become disconnected or the cable clamp may become damaged.
• Take measures to prevent the shaft from rusting. The shafts are coated with anti-rust oil when shipped, but anti-rust oil or grease should also be applied when connecting the shaft to a load.
•
Absolutely do not remove the encoder cover or take the motor apart. The magnet and the encoder are aligned in the Servomotor. If they become misaligned, the motor will not operate.

Ground the motor’s frame to the machine ground when the motor is on a movable shaft.
•
Use a grounding plate for the frame ground for each Unit, as shown in the illustration, and ground to a single point.
•
Use ground lines with a minimum thickness of 3.5 mm
2
, and arrange the wiring so that the ground lines are as short as possible.
• If no-fuse breakers (MCCB) are installed at the top and the power supply line is wired from the lower duct, use metal tubes for wiring and make sure that there is adequate distance between the input lines and the internal wiring. If input and output lines are wired together, noise resistance will decrease.
•
No-fuse breakers (MCCB), surge absorbers, and noise filters (NF) should be positioned near the input terminal block (ground plate), and I/O lines should be isolated and wired using the shortest means possible.
•
Wire the noise filter as shown at the left in the following illustration. The noise filter should be installed at the entrance to the control panel whenever possible.

Selecting Components
This section describes the standards used to select components required to increase noise resistance.
Select these components based on their capacities, performances, and applicable ranges.
Recommended components have been listed; refer to the manufacturer of each component for details.
D
No-fuse Breakers (MCCB)
When selecting no-fuse breakers, take into consideration the maximum input current and the inrush current. The momentary maximum output for a servo system is approximately three times that of the rated output, and a maximum output of three seconds can be executed. Therefore, select no-fuse breakers with an operating time of at least five seconds at 300% of the rated maximum output. Generalpurpose and low-speed no-fuse breakers are generally suitable. Refer to the table in 2-2-3 Terminal
Block Wiring for the power supply input currents for each motor, and then add the current consumption for the number of shafts, other controllers, etc., to make the selection.
The Servo Driver inrush current flows at a maximum of 50 A for 20 ms when 200 V is input. With lowspeed no-fuse breakers, a inrush current 7 to 8 times the rated current flows for 0.1 second. When making the selection, take into consideration the entire inrush current for the system.
D
Surge Absorbers
Use surge absorbers to absorb surges from power supply input lines due to lightning, abnormal voltages, etc. When selecting surge absorbers, take into account the varistor voltage, the amount of surge immunity, and the amount of energy resistance. For 200-VAC systems, use a varistor voltage of 470 V.
The surge absorbers shown in the following table are recommended.

Note 2. Refer to manufacturers documentation for operating details.
Note 3. The surge immunity is for a standard impulse current of 8/20 µ s. If pulses are wide, either decrease the current or change to a larger-capacity surge absorber.
Note 4. The energy resistance is the value for 2 ms. It may not be possible to retard high-energy pulses at less than 700 V. In that case, absorb surges with an insulated transformer or reactor.
D
Noise Filters for Power Supply Input
Use a noise filter to attenuate extraneous noise and to diminish noise radiation from the Servo Driver.
Select a noise filter with a load current of at least twice the rated current. The following table shows noise filters that reduce by 40 dB noise between 200 kHz and 30 MHz.

Remarks
To attenuate noise at frequencies of 200 kH or less, use an insulated transformer and a noise filter. For high frequencies of 30 MHz or more, use a ferrite core and a high-frequency noise filter with a throughtype capacitor.
D
Noise Filters for Motor Output
Use noise filters without built-in capacitors on the Servomotor output lines. Output lines cannot use the same noise filters as the power supply. General-purpose noise filters are made for a power supply frequency of 50/60 Hz; if they are connected to an output of 7.8 to 11 kHz (the Servo Driver PWM frequency), an extremely large leakage current (approx. 100 times normal) will flow to the capacitor in the noise filter. The following table shows the noise filters that are recommended for motor output.

The following table shows types of surge killers and recommended products.
Type
Diode
Features
Diodes are relatively small devices such as relays used for loads when reset time is not an issue. The reset time is increased because the surge voltage is the lowest when power is cut off. Used for 24/48-VDC systems.
Recommended products
Use a fast-recovery diode with a short reverse recovery time.

Select varistor voltage as follows: Thyristor or
Varistor
Thyristor and varistor are used for loads when induction coils are large, as in electromagnetic brakes, solenoids, etc., and when reset time is an issue. The surge voltage when power is cut off is approximately 1.5 times that of the varistor.

Leakage Breakers
Select leakage breakers designed for inverters.
Since switching operations take place inside the Servo Driver, high-frequency current leaks from the armature of the Servomotor. With inverter leakage breakers, high-frequency current is not detected, preventing the breaker from operating due to leakage current.
When selecting leakage breakers, remember to also add the leakage current from devices other than the Servomotor, such as machines using a switching power supply, noise filters, inverters, and so on.
For detailed information about the selection methods of leakage breakers, refer to catalogs provided by manufacturers.
The following table shows the Servomotor leakage currents for each Servo Driver.

Improving Encoder Cable Noise Resistance
Signals from the encoder are either A, B, or S phase. The frequency for A- or B-phase signals is 154 kHz max., while the transmission speed for S-phase signals is 616 kbps. Follow the wiring methods outlined below to improve encoder noise resistance.
•
Be sure to use dedicated encoder cables.
•
If lines are interrupted in the middle, be sure to connect them with connectors, making sure that the cable insulation is not peeled off for more than 50 mm. In addition, be sure to use shielded wire.
•
Do not coil cables. If cables are long and are coiled, mutual induction and inductance will increase and will cause malfunctions. Be sure to use cables fully extended.
•
When installing noise filters for encoder cables, use ferrite cores. The following table shows the recommended ferrite core models.

•
Do not wire the encoder cable in the same duct as power cables and control cables for brakes, solenoids, clutches, and valves.
H
Improving Control I/O Signal Noise Resistance
Position can be affected if control I/O signals are influenced by noise. Follow the methods outlined below for the power supply and wiring.
•
Use completely separate power supplies for the control power supply (especially 24 VDC) and the external operation power supply. In particular, be careful not to connect two power supply ground wires. Install a noise filter on the primary side of the control power supply.
•
Use separate power supplies for control power and for power for the pulse command and deviation counter reset input lines. Do not connect the ground wires for these two power supplies to the same ground.
• We recommend line drivers for the pulse command and deviation counter reset outputs.
•
For the pulse command and deviation counter reset input lines, be sure to use twisted-pair shielded cable, and connect both ends of the shield wire to ground.
2-30
System Design and Installation Chapter 2
•
If the control power supply wiring is long, noise resistance can be improved by adding 1-
µ
F laminated ceramic capacitors between the control power supply and ground at the Servo Driver input section and the controller output section.
• For encoder output (A, B, and Z phase) lines, be sure to use twisted-pair shielded cable, and connect both ends of the shield wire to ground.
•
Wiring must be 1 m or less when using open-collector outputs.

2-3-3 Wiring Products Conforming to EMC Directives
Models conforming to EC Directive will meet the requirements of the EMC Directives EN55011 Class A
Group 1 (EMI) and EN50082-2 (EMS) if they are wired under the conditions described in this section. If the connected devices, wiring, and other conditions cannot be made to fulfill the installation and wiring conditions when the product is incorporated into a machine, the compliance of the overall machine must be confirmed.
The following conditions must be met to conform to EMC Directives.
•
The Servo Driver must be installed in a metal case (control panel).
• Noise filters and surge absorbers must be installed on all power supply lines.
•
Shielded cables must be used for all I/O signal lines and encoder lines. (Use tin-plated, soft copper wires for the shield weaving.)
•
All cables leaving the control panel must be wired in metal ducts or conduits with blades.
•
Ferrite cores must be attached to the shielded cable and the shield must be clamped directly to the ground plate to ground it.

No-fuse Breakers (MCCB)
When selecting no-fuse breakers, take into consideration the maximum output current and the inrush current. The momentary maximum output for a servo system is approximately three times that of the rated output, and a maximum output of three seconds can be executed. Therefore, select no-fuse breakers with an operating time of at least five seconds at 300% of the rated maximum output. Generalpurpose and low-speed no-fuse breakers are generally suitable. Refer to the table in 2-2-3 Terminal
Block Wiring for the power supply input currents for each motor, and then add the current consumption for the number of shafts, other controllers, etc., to make the selection.
The Servo Driver inrush current flows at a maximum of 50 A for 20 ms when 200 V is input. With lowspeed no-fuse breakers, a inrush current 7 to 8 times the rated current flows for 0.1 second. When making the selection, take into consideration the entire inrush current for the system.
D
Surge Absorbers
Use surge absorbers to absorb surges from power supply input lines due to lightning, abnormal voltages, etc. When selecting surge absorbers, take into account the varistor voltage, the amount of surge immunity, and the amount of energy resistance. For 200-VAC systems, use a varistor voltage of 470 V.
The surge absorbers shown in the following table are recommended.

The following table shows types of surge killers and recommended products.
Type
Diode
Features
Diodes are relatively small devices such as relays used for loads when reset time is not an issue. The reset time is increased because the surge voltage is the lowest when power is cut off. Used for 24/48-VDC systems.
Recommended products
Use a fast-recovery diode with a short reverse recovery time.
Fuji Electric Co., ERB44-06 or equivalent
Select varistor voltage as follows: Thyristor or
Varistor
Thyristor and varistor are used for loads when induction coils are large, as in electromagnetic brakes, solenoids, etc., and when reset time is an issue. The surge voltage when power is cut off is approximately 1.5 times that of the varistor.
24-VDC system varistor: 39 V
100-VDC system varistor: 200 V
100-VAC system varistor: 270 V
200-VAC system varistor: 470 V
Capacitor
+ resistor
Use capacitors and resistors for vibration absorption of surge when power is cut off. The reset time can be shortened by proper selection of the capacitor or resistor.

Leakage Breakers
•
Select leakage breakers designed for inverters.
•
Since switching operations take place inside the Servo Driver, high-frequency current leaks from the armature of the Servomotor. With inverter leakage breakers, high-frequency current is not detected, preventing the breaker from operating due to leakage current.
•
When selecting leakage breakers, also remember to add the leakage current from devices other than the Servomotor, such as machines using a switching power supply, noise filters, inverters, and so on.
• For detailed information about the selection methods of leakage breakers, refer to catalogs provided by manufacturers.
•
The following table shows the Servomotor leakage currents for each Servo Driver.
Driver Leakage current (direct)
(including high-frequency current)

R88D-UA20V 110 mA 5 mA
Note 1. Leakage current values shown above are for motor power lines of 10 m or less. The values will change depending on the length of power cables and the insulation.
Note 2. Leakage current values shown above are for normal temperatures and humidity. The values will change depending on the temperature and humidity.

Note 3. Leakage current for 100-VAC-input Servomotors is approximately half that of the values shown above.

Improving Encoder Cable Noise Resistance
The following encoder signals are used: A, B, and S phase. The frequency for A- or B-phase signals is
154 kHz max.; the transmission speed for S-phase signals is 616 kbps.
Follow the wiring methods outlined below to improve encoder noise resistance.
•
Be sure to use dedicated encoder cables.
•
If lines are interrupted in the middle, be sure to connect them with connectors, making sure that the cable insulation is not peeled off for more than 50 mm. In addition, be sure to use shielded wire.
•
Do not coil cables. If cables are long and are coiled, mutual induction and inductance will increase and will cause malfunctions. Be sure to use cables fully extended.
•
When installing noise filters for encoder cables, use ferrite cores. The following table shows the recommended ferrite core models.

Maker Name
EMI core
Clamp filter
Model
ESD-QR-25-1
ZCAT2032-0930
ZCAT3035-1330
ZCAT2035-0930A
•
Do not wire the encoder cable in the same duct as power cables and control cables for brakes, solenoids, clutches, and valves.
H
Improving Control I/O Signal Noise Resistance
Position can be affected if control I/O signals are influenced by noise. Follow the methods outlined below for the power supply and wiring.
•
Use completely separate power supplies for the control power supply (especially 24 VDC) and the external operation power supply. In particular, be careful not to connect two power supply ground wires. Install a noise filter on the primary side of the control power supply.
•
For speed and torque command input lines, be sure to use twisted-pair shielded cable, and connect both ends of the shield wire to ground.
•
If the control power supply wiring is long, noise resistance can be improved by adding 1-
µ
F laminated ceramic capacitors between the control power supply and ground at the Servo Driver input section and the controller output section.
•
For encoder output (A, B, and Z phase, plus the absolute encoder signal) lines, be sure to use twistedpair shielded cable, and connect both ends of the shield wire to ground.

Function
• This function controls Servomotor speed using the speeds set in the parameters (No. 1, No. 2, and
No. 3 internal speed settings).
•
The internal speed is selected with control input terminals CN1-11 and CN1-12 (speed selection commands 1 and 2). The direction of rotation is specified with CN1-15 (the rotation direction command).
• When both speed selection commands 1 and 2 are OFF, the motor will decelerate to a stop in the software start deceleration time (specified in Cn-23) and then go into servo lock status.
Depending on the parameter settings, it might be possible to perform position control in this status using pulse-train inputs. (HA/LA/V/W Models)

In this control mode, it is possible to perform speed control using the internal speed control settings as well as position control using the pulse-train inputs.
•
When both SPD1 and SPD2 are OFF, the motor will be decelerated, the positioning completion output will be output, and the servo will enter servo lock status. It will still be possible to receive pulse command inputs in servo lock status.

•
The motor will be driven with a pulse determined by multiplying the command pulse count by the electronic gear ratio.
•
The electronic gear is useful for the following applications:
S To fine-tune the position and speed of two lines that must be synchronized.
S
When using a positioner with a low command pulse frequency.
S To set the machine movement per pulse to a specific value, such as 0.01 mm.

•
The electronic gear is set as G1 divided by G2 (G1/G2). G1 is set in user parameter Cn-24; G2 is set in Cn-25. The target pulse count is computed as follows:
Target pulse count = Command pulse count x G1/G2
•
If G1/G2 = 1, the motor will turn once for every 8,192 command pulses (driver running at a factor of
4X).
•
One pulse for the position deviation (deviation counter) display and positioning completion range will be equivalent to one input pulse (here the unit is said to be the command).

Note 2. As the bias rotational speed increases, Servomotor rotation becomes more unstable. The optimal value changes depending on the load, gain, and positioning completion range, so observe the response while making the adjustment. Start with the bias rotational speed set to 0 and slowly increase it.

Function
•
This function limits the Servomotor’s output torque.
•
This function can be used to protect the Servomotor and machine system by preventing excessive force or torque on the machine system when the machine (moving part) pushes against the workpiece with a steady force, such as in a bending machine.
•
There are two methods for limiting the torque:
1. Limit the steady force applied during normal operation with user parameters Cn-08 (forward torque limit) and Cn-09 (reverse torque limit).
2. Limit operation with external signals connected to pins CN1-11 (PCL: forward current limit input) and CN1-12 (NCL: reverse current limit input). Set user parameters Cn-18 ( forward rotation external current limit ) and Cn-19 (reverse rotation external current limit ).

(Cn-15), or if the time set for brake timing 2 (Cn-16) elapses after the Servomotor stops receiving power, the brake interlock signal (BKIR) will turn OFF.

Operation Chapter 3
D
Position Loop Gain
The responsiveness of the servo system is determined by the position loop gain. When a servo system has high position loop gain, the responsiveness is greater and positioning can be faster. In order for position loop gain to be raised, the mechanical rigidity and the characteristic frequency must be increased. For general NC machine tools, the range is 50 to 70 (1/s); for general machinery and assembly devices, it is 30 to 50 (1/s); for industrial robots, it is 10 to 30 (1/s). The factory setting for position loop gain is 40 (1/s), so it should be lowered for systems with low rigidity.
Position loop gain is generally expressed as follows:
Position loop gain (Kp) =
Instruction command frequency (pulses/s)
Deviation counter’s residual pulse amount (pulses)
(1/s)
In addition, the system response setting is 1/Kp, so in order to increase the responsiveness, it is necessary to increase the position loop gain. If a system has low rigidity or low characteristic frequency, increasing the position loop gain sympathetic vibration of machinery will occur and an alarm will be generated.
If position loop gain is low, positioning time can be improved by using feed-forward control.
In addition to this method, positioning completion can be speeded up by using the bypass function.

Increasing the positioning completion range too much can cause the positioning completion output to turn ON during lowspeed operation or other times when there are few residual pulses.
0 to 450 Used to reduce positioning time.
Positioning time will be decrease as the bias rotational speed is increased, but will become unstable if it is increased too much. Increase the value gradually from 0 and observe the affect on the system.

Feed-forward Amount
The feed-forward amount is effective when the position loop gain is set to less than 25 l/s. It will not be very effective when the position loop gain is higher than 25 l/s.
3-38
Time
Operation Chapter 3
Increasing the feed-forward amount to much will cause excessive overshooting.
The feed-forward amount is not sent through the deviation counter, but is applied directly to the speed loop. The differential of the deviation counter is thus not applied, causing a faster response when the load response is delayed from the commands.
Be sure that the position loop is completely adjusted and that the speed loop is operating safely before adjusting the feed-forward amount.
Increasing the feed-forward amount too much will cause the speed command to oscillate, resulting in abnormal noise from the motor. Increase the feed-forward amount slowly from 0%, adjusting it so that the positioning completion output is not adversely affected (e.g., turn repeatedly ON and OFF) and so that the speed does not overshoot.

Sets the level for detection of deviation counter overflow.
The residual pulses in the deviation counter will equal the command pulse frequency divided by the position loop gain. Divide this value by 256, add a reasonable amount of leeway, and set the deviation counter overflow level to the resulting value.
× 0.1 ms 0 to 640 Sets the time constant for smoothing (position command soft start function).
Even if the position command pulses are input in steps, the time constant set here will be used to accelerate/decelerate the motor.
The same time will be used for both acceleration and deceleration.
Set this parameter to 0 when using a position controller that has an acceleration/deceleration function.
× 0.1 ms 0 to 640 Sets the feed-forward command filter.
This parameters acts as a low-pass filter to prevent the feed-forward amount from being applied too quickly when position command pulses are input in steps.
--0 to 100 Decreases the speed loop gain by the set value when a large torque is output due to acceleration, deceleration, etc.
D
Compensating Gain
Increasing the compensating gain will reduce motor vibration and will also enable setting a larger speed loop gain, allowing faster positioning. Increasing the compensating gain too much will delay following accelerations/decelerations.
Adjust the compensating gain only after adjusting the speed loop gain (Cn-04) and the speed loop integration constant (Cn-05).
Depending on the values of the speed loop gain (Cn-04) and the speed loop integration constant
(Cn-05), the upper limit of the compensating gain may be 100 or less. An error will occur if the compensating gain is set too high.

3-8 Regenerative Energy Absorption
Regenerative energy produced at times such as Servomotor deceleration is absorbed by the Servo Driver’s internal capacitors, thereby preventing an increase in DC voltage.
If the regenerative energy from the Servomotor becomes too large, however, an overvoltage error will occur. In such cases, it is necessary to connect a Regeneration Unit to increase the capacity for absorbing regenerative energy.

Regenerative Energy Absorbed Internally
The Servo Driver absorbs regenerative energy by means of an internal capacitor. If there is more regenerative energy than can be absorbed by the capacitor, an overvoltage error will be generated and operation cannot continue. The amounts of regenerative energy that can be absorbed by the various Servo
Drivers alone are shown in the tables below. If regenerative energy exceeding these values is produced, take the following measures.
•
Connect a Regeneration Unit (R88A-RG08UA) (Refer to 3-8-3). (Models Conforming to UL/cUL

•
Lower the operating rotation speed. (The regenerative energy is proportional to the square of the rotation speed.)
•
Lengthen the deceleration time. (Reduce the amount of regenerative energy per unit time.)

If an external force acts in the same direction as the Servomotor rotation, due to factors such as the fall time on the vertical shaft, be sure to measure the regenerative energy and check to see that the amount that can be absorbed is not exceeded.

Regeneration Resistor (Models Conforming to UL/cUL
Standards and Models Not Conforming to Any
Standards)
Connect one or more external regeneration resistors when a Regeneration Unit (R88A-
RG08UA) cannot absorb all of the regenerative energy. Remove the short bar from between the RG and JP terminals on the Regeneration Unit and connect the resistor between the P and RG terminals. Connecting to the wrong terminals may destroy the Regeneration Unit, so connect the resistor carefully. (The Regeneration Unit does not conform to EC Directives.)
The external regeneration resistor will heat to approximately 120

Operation Chapter 3
3-8-4 Processing Regenerative Energy with Multiple Axes
(Models Conforming to EC Directives)
When using multiple axes, the + terminals on the Servo Drivers can be connected together and the – terminals can be connected together to use regenerative energy as the drive energy for the other axes, thus absorbing the energy. Servo Drivers with different power supply voltages, however, cannot be connected. Also, regeneration absorption capacity will not be increased when all axes simultaneously produce regenerative energy.
H
Wiring Method (Example for 3 Axes)
Axis 1 Axis 2 Axis 3
Note 1. Do not open or close the connections between the + or – terminals while power is being supplied. The Units may be destroyed.
Note 2. Do not connect Servo Drivers that are using different power supply voltages. The Units may be destroyed.
Regeneration absorption capacity will not be increased when all axes simultaneously produce regenerative energy. Take one or more of the following methods if this occurs.
•
Reduce the number of rotations being used. (Regenerative energy is directly proportional to the square of the number of rotations.)
•
Increase the deceleration time. (This will reduce the regenerative energy per unit time.)

4-3-3 Overload Characteristics (Electron Thermal
Characteristics)
Chapter 4
An overload protection function (electron thermal) is built into the Servo Driver to protect against Servo Driver or Servomotor overload. If an overload (A.70 to A.72) does occur, first clear the cause of the error and then wait at least one minute for the Servomotor temperature to drop before turning on the power again. If the power is turned on again too soon, the Servomotor coil may be damaged.

Chapter 4
!
WARNING
Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so may result in malfunction, fire, or electric shock.
!
Caution Resume operation only after transferring to the new Unit the contents of the data required for operation. Not doing so may result in an unexpected operation.
Servo Motors and Drives contain many components and will operate properly only when each of the individual components is operating properly. Some of the electrical and mechanical components require maintenance depending on application conditions. In order to ensure proper long-term operation of Servo Motors and Drivers, periodic inspection and part replacement is required according to the life of the components.
The periodic maintenance cycle depends on the installation environment and application conditions of the Servo Motor or Driver. Recommended maintenance times are listed below for Servo Motors and
Drivers. Use these are reference in determining actual maintenance schedules.
H
Servo Motors
•
Recommended Periodic Maintenance
Oil Seal: 2,000 hours
Bearings: 20,000 hours
Application Conditions: Ambient motor operating temperature of 40
_
C, within allowable shaft load, rated operation (rated torque and r/m), installed as described in operation manual.
•
The radial loads during operation (rotation) on timing pulleys and other components contacting belts is twice the still load. Consult with the belt and pulley manufacturers and adjust designs and system settings so that the allowable shaft load is not exceeded even during operation. If a motor is used under a shaft load exceeding the allowable limit, the motor shaft can break, the bearings can burn out, and other problems can occur.
H
Servo Driver and Regeneration Units
• Recommended Periodic Maintenance
Aluminum analytical capacitors: 50,000 hours
Application Conditions: Ambient driver (regeneration unit) operating temperature of 55 _ C, rated operation (rated torque), installed as described in operation manual.
• The life of aluminum analytical capacitors is greatly affected by the ambient operating temperature.
Generally speaking, an increase of 10
_
C in the ambient operating temperature will reduce capacitor life by 50%. We recommend that ambient operating temperature be lowered and the power supply time be reduced as much as possible to lengthen the maintenance times for Servo Drivers and Regeneration Units.
•
It is recommended that the Servo Driver and Regeneration Unit be inspected at five-year intervals if they are used under conditions worse than the above or not used over a long time of time. Contact your
OMRON representative for inspection and the necessity of any component replacement.

Run Command (14: RUN)
This is the input that turns on the power drive circuit for the main circuit of the Servo Driver. If this signal is not input (i.e., servo-off status), the Servomotor cannot operate. Depending on the setting of setup parameter Cn-01, bit no. 0, this signal can be bypassed. In that case, the servo will be turned on after the power is turned on.
D
Gain Reduction (15: MING), Pulse Stop (15: IPG),
Rotation Direction Command (15: RDIR)
This input signal can be switched among the following three kinds of signals by changing on the settings of bit 2 of setup parameter Cn-02 and bit F of setup parameter Cn-01. Select the signal function required for your application.
•
Gain Reduction (15: MING; Cn-02 Bit No. 2 = 0 and Cn-01 Bit No. F = 0)
Bit F of Cn-01 can be set in HA/LA/V/W Models only. Input this signal to lower the loop gain for the control loop, and to weaken servo rigidity (repellant force with respect to external force).
When the gain reduction is input, speed loop integration is disabled, decreasing the speed loop gain.
In addition, when parts are inserted after positioning, the insertion operation is made easier because the repellant force with respect to external force is weakened by the inputting of this signal. This cannot be used for the vertical shaft where a gravity load is applied, because position deviation will occur.
•
Pulse Stop (15: IPG; Cn-02 Bit No. 2 = 0 and Cn-01 Bit No. F = 1)
This signal can be used in HA/LA/V/W Models only. Command signals won’t be received internally while this signal is ON.
•
Rotation Direction Command (15: RDIR; Cn-02, Bit No. 2= 1)
This signal becomes the rotation direction change command for when operation is carried out at the internally set speed (no. 1 through no. 3 internally set speeds). When this signal is not input, the rotation direction is forward; when it is input, the direction is reverse.
D
Forward Drive Prohibit (16: POT, Cn-01 bit No. 2 = 0)
Reverse Drive Prohibit (17: NOT, Cn-01 bit No. 3 = 0)
These two signals are the inputs for forward and reverse drive prohibit (overtravel). When they are input, driving is possible in the respective directions. When driving is prohibited, movement will stop ac-

Specifications Chapter 5 cording to the settings of bits nos. 6, 8, and 9 of setup parameter no. 1 (Cn-01). Alarm status will not be generated at the Driver. When drive prohibition is not used, clear the function by connecting the respective signal to the external power supply +24-V GND or setting setup parameter Cn-01, bit nos. 2, 3 = 1,1.

Forward/Reverse Rotation Current Limit [11, 12: (PCL/SPD1), (NCL/SPD2)]
These input signals switch between the forward/reverse current limit and the speed selection command signal for the internally set speed, depending on the setting of setup parameter Cn-02 bit no. 2. Set the required functions for using it.
•
Forward/Reverse Rotation Current Limit (11, 12: PCL, NCL)
When setup parameter Cn-02 bit no. 2 = 0, these input signals become respectively the forward rotation current limit and the reverse rotation current limit, and they limit the current to the Servomotor.
The current limit values can be set for the respective directions by means of user parameters Cn-18 and 19.
•
Speed Selection Command (11, 12: SPD1, SPD2)
When setup parameter Cn-02 bit no. 2 = 1, these input signals become the speed selection command 1 and the speed selection command 2. Depending on the combination, the Servomotor speed can be controlled according to the internally set speeds, nos. 1 through 3, which are set in user parameter Cn-1F, 20, 21. At that time, the CN1-15 pin becomes the rotation direction command (RDIR).
D
Alarm Reset (18: RESET)
This is the external reset signal input for the servo alarm. The alarm is reset when the signal turns ON.
Remove the cause of the alarm and then restart operation. In order to prevent danger, turn OFF the run command before inputting the reset signal.

Rotation Direction Change (7: DIR)
To set up the mechanical configuration so that a + voltage input causes reverse rotation instead of forward rotation, this terminal can be connected to the E0V terminal for any of pins 1 through 3 (encoder power supply GND terminal). This function carries out the same operation by means of setting setup parameter Cn-02 bit no. 0 to “1.” Use this to prevent runaway when replacing the Servo Driver.
5-21
Specifications Chapter 5
When the rotation direction is changed, the encoder A-phase and B-phase output phases are also changed. When not set, + voltage is for forward rotation and A-phase advance; when set, + voltage if for reverse rotation and A-phase advance (and - voltage is for forward rotation and B-phase advance).
Therefore wiring changes are unnecessary for encoder signals to the position controller.

Refer to 3-4-2 Setup Parameter Contents and 3-5-2 User Parameter Chart for a table of user parameters and setup parameters.
D
Speed Loop Gain: Cn-04
This is the proportional gain for the speed controller. The adjustable range is 1 to 2,000 Hz (the response frequency when equivalent inertia is used). As the number is increased, the gain is increased.
The factory setting is for 80 (Hz). Using the factory setting for the Servomotor alone or with a small load inertia will cause vibration to occur, so set the value to a maximum of 20 (Hz) for operation.
D
Speed Loop Integration Constant: Cn-05
This is the integration time for the speed controller. The adjustable range is 2 to 10,000 (ms), and it is factory set to 20 (ms). As the number is increased, the gain is decreased. The unit can be changed using the integration time constant setting unit (Cn-02 bit No-b). (HA/LA/V/W Models)
D
Emergency Stop Torque: Cn-06
When setup parameter Cn-01 bit no. 8 = 1, this sets the braking torque for over-travel stopping (forward/ reverse drive prohibit input operation). The setting range is 0 to the maximum torque (a percentage of the braking torque as 100% of the Servomotor rated torque). The factory setting is for the maximum torque.
D
Software Start Acceleration Time: Cn-07
Software Start Deceleration Time: Cn-23
The Servomotor rotation acceleration time from 0 r/min to 4,500 r/min is set in Cn-07, and the deceleration time from 4,500 r/min to 0 r/min is set in Cn-23. The factory setting is for 0 (ms). Set the acceleration and deceleration times to 0 (ms) unless using the internal speed settings.
5-23
Specifications Chapter 5
D
Forward Torque Control: Cn-08
Reverse Torque Control: Cn-09
The Servomotor output torque control value for forward rotation is set in Cn-08, and the value for reverse rotation is set in Cn-09. The setting range is 0 to the maximum torque, and the factory setting is for the maximum torque.
D
Encoder Divider Rate: Cn-0A
The number of pulses detected (A- and B-pulses) per encoder revolution is converted to the number of pulses set for this parameter and output from the Servo Driver. The setting range is 16 to 2,048 pulses/ revolution, and the factory setting is for 1,000 (pulses/revolution).
D
Rotational Speed for Servomotor Rotation Detection: Cn-0b
This sets the rotational speed for detecting whether or not the Servomotor is rotating. The setting range is 1 to 4,500 r/min. When motor rotation detection has been set for the sequence output signal switch
(Cn-01 bit 4 = 0), the Servomotor rotation detection output (TGON: CN1-9) is turned ON if the Servomotor rotational speed meets or exceeds this set value. The factory setting is for 20 (r/min).
D
P Control Switching (Torque Command): Cn-0C
P Control Switching (Speed Command): Cn-0d
P Control Switching (Acceleration Command): Cn-0E
P Control Switching (Deviation Pulse): Cn-0F
These set the various points for switching the speed controller from PI control to P control in order to moderate excessive characteristics when an operation such as acceleration or deceleration is executed accompanied by output saturation of the controller. These selections are made by setting the setup parameter Cn-01 bit nos. b, d and C.
D
Jog Speed: Cn-10
This sets the speed for manual operation. The setting range is 0 to 4,500 r/min. During manual operation, operating commands are given from the Parameter Unit. The factory setting is for 500 (r/min).
D
Number of Encoder Pulses: Cn-11
This sets the number of pulses per revolution of a connected encoder. Do not change this parameter’s setting; the Servomotor might not operate correctly if it is changed. The factory setting is for 2,048
(pulses/revolution).
D
Brake Timing 1: Cn-12
Brake Command Speed: Cn-15
Brake Timing 2: Cn-16
These parameters determine the output timing of the brake interlock signal (BKIR), which controls the electromagnetic brake.
Brake timing 1 sets the delay time from the time of brake interlock goes OFF until the servo turns off. The setting range is 0 to 50 (
×
10 ms), and the factory setting is for 0 (
×
10 ms).
The brake command speed is the speed (r/m) used to turn OFF the brake interlock. The setting range is
0 to 4,500 (r/m) and the factory setting is for 100 (r/m).
Brake timing 2 sets the wait time from when the servo goes OFF until the brake interlock goes OFF. The setting range is 10 to 100 (
×
10 ms), and the factory setting is for 50 (
×
10 ms).
5-24
Specifications Chapter 5
If the run command turns off , a servo error occurs, or the main-circuit power supply turns off during operation of a Servomotor with a brake, the dynamic brake comes on (setup parameter Cn-01 bit no. 6 =
0) and Servomotor rotation speed is decreased. When the speed drops to the level of the value set for the brake command speed (Cn-15), the brake interlock output (BKIR: CN1-7) turns OFF.
Even if the speed does not drop to the level of the value set for the brake command speed (Cn-15), the brake interlock output (BKIR: CN1-7) turns OFF after the time set for brake timing 2 has elapsed. (This time setting is made for the purpose of preventing damage to machinery or the Servomotor holding brake.)
D
Torque Command Filter Time Constant: Cn-17
This sets the low-pass filter time constant for the torque command. The setting range is 0 to 250 (
×
100
µ s), and the factory setting is 4 (
×
100
µ s).
The relationship between the filter time constant and the cut-off frequency can be found by means of the following formula: fc (Hz) = 1 / (2
πΤ
) :
Τ
= Filter time constant
If
Τ
= 400 (
µ s), fc will be approximately 400 (Hz).
When the characteristic vibration of the machinery is within the response frequency of the servo loop,
Servomotor vibration will occur. In order to prevent this sympathetic vibration based on the characteristic vibration of the machinery, set the torque filter time constant to a value that will eliminate the vibration
(i.e., set it to a high value).
D
Forward Rotation External Current Limit: Cn-18
Reverse Rotation External Current Limit: Cn-19
These set the Servomotor output torque limits for the forward and reverse directions. They are valid when the forward/reverse current limits (PCL/NCL CN1-11/12) are input. This function can’t be used if the input command mode is set to “internal speed control settings.” The setting range is 0 to the maximum torque, and the factory setting is for the 100 (%).
D
Position Loop Gain: Cn-1A
Adjust the position loop gain to the rigidity of the machine. Set to between 50 and 70 (1/s) for general NC machine tools, to between 30 and 50 (1/s) for general and assembly machines, and to 10 to 30 (1/s) for industrial robots.
Load alarms will be caused by machine oscillation if the position loop gain is increased for systems with low rigidity or systems with intrinsically low-frequency vibration.
The setting range is 1 to 500 (1/s), and the factory setting is 40 (1/s).
D
Positioning Completed Range: Cn-1b
This sets the deviation counter value for outputting the positioning completed output (INP). When the deviation counter value falls below this setting, the positioning completed output turns ON. The setting range is 0 to 250 (command units), and the factory setting is 3 (command units).
D
Bias Rotational Speed: Cn-1C
This is the setting for position control bias. Use this setting according to the load conditions in order to shorten positioning time. The setting range is 1 to 450 (r/min), and the factory setting is 0 (r/min).
5-25
Specifications Chapter 5
D
Feed-forward Amount: Cn-1d
This is the feed forward compensation for the position controller. Positioning time is shortened by adding the command pulse differential to the speed command. The setting range is 0 to 100%, and the factory setting is 0%.
D
Deviation Counter Overflow Level: Cn-1E
This sets the level for detection deviation counter overflow. If the deviation counter value exceeds this set value, a servo alarm will be generated. The setting range is 1 to 32,767 (
×
256 command units), and the factory setting is 1,024 ( × 256 command units).
D
No. 1 Internal Speed Setting: Cn-1F (Factory Setting: 100 r/min)
No. 2 Internal Speed Setting: Cn-20 (Factory Setting: 200 r/min)
No. 3 Internal Speed Setting: Cn-21 (Factory Setting: 300 r/min)
Make these settings to control speeds by means of internal settings. The setting range is 0 to 4,500
(r/min). For details, refer to 3-5-3 Setting Internal Speed Control.
D
Electronic Gear Ratio G1 (Numerator): Cn-24
Electronic Gear Ratio G2 (Denominator): Cn-25
The motor will be operated by the pulses resulting from the number of command pulses multiplied by the gear ratio (G1/G2).
The setting range for both G1 and G2 is 65,535, and the settings are restricted as follows:
(1/100) x
(G1/G2) x
100.
The factory setting is : G1 =4, G2 = 1 (i.e., an electronic gear ratio of 4/1). At the factory setting, inputting
2,048 pulses will cause one Servomotor revolution.
D
Position Command Acceleration/Deceleration Time Constant: Cn-26
This executes smoothing processing on command pulses for Servomotor operation. It is valid in the following cases:
•
There is no acceleration or deceleration for command pulses.
• The command pulse frequency changes suddenly.
•
The electronic gear ratio setting is large (G1/G2 y
10).
The setting range is 0 to 640 ( × 0.1 ms), and the factory setting is 0 ( × 0.1 ms).
D
Feed Forward Command Filter: Cn-27
This is the setting for the low-pass filter so that the feed forward amount is not added suddenly. Using this setting can prevent overshooting in the event of sudden changes in command pulse frequency. The setting range is 0 to 640 (
×
0.1 ms), and the factory setting is 0 (
×
0.1 ms).
D
Compensating Gain: Cn-28 (HA/LA/V/W Models)
When outputting a large torque (during acceleration, deceleration, etc.), the speed loop gain is decreased based on this setting. Motor vibration can be reduced by increasing this setting; also, the positioning time can be reduced because the speed loop gain can be set to a higher value.
If this setting is too high, follow-up delays can occur during acceleration and deceleration. The setting range is 0 to 100, and the factory setting is 0.
5-26
Specifications Chapter 5
Adjust the compensation gain after adjusting the speed loop gain with Cn-04 and the speed loop integral time constant with Cn-05.
The compensation gain may not be 100 due to the speed loop gain and speed loop integral time constant set with Cn-04 and Cn-05, in which case increasing the compensation gain will cause an error.
Make sure that the set value is 0 before performing auto-tuning. Proper gain adjustment may not be possible with auto-tuning if the set value is not 0.
D
Unit Number Setting: Cn-29 (HA/LA/V/W Models)
This setting specifies the Servo Driver’s unit number when communicating with a personal computer.
Set the unit number to 0 when communicating with a single axis. Set the unit number from 1 to 14 when communicating with multiple axes; in this case, be sure not to use the same unit number for more than one Unit. The Servo Driver or personal computer might be damaged if the same unit number is used for more than one Unit. The setting range is from 0 to14, and the factory setting is 0.
Refer to the Computer Monitor Software Instruction Manual (I513) for OMNUC U-series Servo Drivers for more details on the unit number setting.

AC Servomotor Heat Radiation Conditions
When an AC Servomotor is continuously operated at the rated conditions, a heat radiation plate equivalent to an rectangular aluminum plate of t6
×
250 mm is required at the Servomotor flange mounting area. (This is for horizontal mounting, with nothing around the Servomotor and no interference from heat convection currents.)

Specifications for Servomotors with Magnetic Brakes
Chapter 5
The magnetic brakes installed in Servomotors with brakes are status-holding brakes with non-magnetized operation. The magnetic brake is released when a magnetic current (24 VDC) is applied. The magnetic brake is not meant to be used for braking. Using it for braking will damage it. During Servomotor operation, be sure to release the magnetic brake by applying a magnetic voltage. The specifications for Servomotors with brakes are similar to those for Servomotors without brakes, so except for inertia and weight, the various constants are all the same.
Note: The inertia for magnetic brakes is the load inertia.

Servomotor and Mechanical System Temperature Characteristics
•
U-series AC Servomotors use rare earth magnets (neodymium-iron magnets). The temperature coefficient for these magnets is approximately -0.13%/ ° C. As the temperature drops, the Servomotor’s momentary maximum torque increases, and as the temperature rises the Servomotor’s momentary maximum torque decreases. When the normal temperature of 20 ° C and -10 ° C are compared, the momentary maximum torque increases by approximately 4%. Conversely, when the magnet warms up to 80
°
C from the normal temperature of 20
°
C, the momentary maximum torque decreases by approximately 8%.
•
Generally, in a mechanical system, when the temperature drops the friction torque increases and the load torque becomes larger. For that reason, overloading may occur at low temperatures. In particular, in systems which use deceleration devices, the load torque at low temperatures may be nearly twice the load torque at normal temperatures. Check with a current monitor to see whether overloading is occurring at low temperatures, and how much the load torque is. Likewise, check to see whether there abnormal Servomotor overheating or alarms are occurring at high temperatures.
•
An increase in load friction torque increases the apparent load inertia. Therefore, even if the Servo
Driver parameters are adjusted at a normal temperature, there may not be optimal operation at low temperatures. Check to see whether there is optimal operation at low temperatures too.

Note 3. The allowable radial and thrust loads are values determined with a service life of 20,000 hours taken as a criteria.
Note 4. The service life of bearing grease is 20,000 hours at a Servomotor ambient temperature of
40
°
C, and under the rated operating conditions.
Note 5. Absolutely do not impact the Servomotor or the output shaft by striking them with an implement such as a hammer. Doing so will damage the Servomotor and encoder bearings.
Note 6. Make sure that the radial load is within the allowable range when there is a radial load applied.
If the Servomotor is operated at more than the allowable radial load, the shaft may suffer damage due to fatigue.
Note 7. Applying an excessive load even once can damage the bearings and eventually cause a breakdown.

Note 1. Incorrect signal wiring can cause damage to Units and the Servo Driver.
Note 2. Leave unused signal lines open and do not wire them.
Note 3. ERB44-02 diodes (by Fuji Electric) or equivalent are recommended for surge absorption.
Note 4. When using a 3G2A5-NC111-EV1 Position Control Unit, origin search is carried out according to the origin and origin proximity inputs. Set the origin and origin proximity for the mechanical system. Even after the 3G2A5-NC111-EV1 completes the origin search and pulses are stopped, pulses are still accumulated in the deviation counter in the Servo Driver. The Servomotor will move for the amount of residual pulses and then stop, so there may be a discrepancy with the origin. In order to minimize the amount of the discrepancy, set the origin search proximity speed as low as possible.
Note 5. Use the RUN signal to set whether the Servo can be turned ON/OFF.

Setting
Note 1. Cn-04 (speed loop gain) is factory-set for three times the load inertia. Therefore, if the load inertia is extremely small, some oscillation may occur. If it does, then lower Cn-04 to 20 or less.
Note 2. After the settings for Cn-11 (number of encoder pulses), Cn-24 (Electronic gear ratio G1 (numerator)), and Cn-25 (Electronic gear ratio G2 (denominator)) have been made, they become effective when the power is turned on again after having been cut off. (Check to see that the
LED display has gone off.)
Note 3. Set Cn-11 (number of encoder pulses) according to the number of pulses (resolution) of the encoder. The parameter must be set to 2,048 for an incremental encoder.
Note 4. Refer to the Computer Monitor Software Instruction Manual (I513) for OMNUC U-series
Servo Drivers for more details on Cn-29 (unit number setting).

Note 1. If power is immediately turned back on after having been cut off, a momentary stop alarm may be generated. If bit no. 5 is set to “1,” the alarm will be cleared automatically even if it is generated, and operation will resume.
Note 2. If set bit 6 to “1” and bit 8 to “0,” the dynamic brake relay will turn OFF after the Servomotor stops, regardless of the setting of bit no. 7.
Note 3. With P control switch conditions, a change from PI control to P control is selected.
Note 4. Do not change the setting of bits 1 and E of setup parameter no. 1 (Cn-01) when a Servomotor with an incremental encoder is being used.
Note 5. These parameters become effective only after power is reset. Confirm that the indicators go out before turning power back on. (Check to see that the LED display has gone off.)
