1.3 AC Drive Application Precautions
1.3.1 AC Drive Selection
1.3.1.1 Drive Capacity
Before driving motors, ensure the motor rated current is lower than the drive rated output. In addition, when a single AC drive is driving more than 1 motor in parallel, make sure the drive capacity is higher than 110% of total motor rated current.
1.3.1.2 Starting Torque
8
The motor characteristics at start and during acceleration are limited by the drive overcurrent.
If higher starting torque is needed, use a higher rating drive or increase capacity of both motor and drive.
1.3.1.3 Emergency Stop
When a drive fault occurs, protection function will be automatically triggered to shut off the output but the motor may not stop immediately. Therefore please install mechanical brake if immediate stop is necessary.
1.3.2 Settings
1.3.2.1 Upper Limits
The maximum output frequency of the drive is 400Hz. If the upper limit is set incorrectly, the motor will run at higher than its rated speed and cause danger. Please set the limit of output frequency in Frequency Upper Limit parameter. The default setting of the rated output frequency is 60Hz.
1.3.2.2 DC Braking
Excessive DC braking current and duration could cause motor overheat.
1.3.2.3 Acceleration /Deceleration Time (Acc./Dec. Time)
Acceleration and deceleration time is determined by the motor torque, load torque and load inertia. Set a longer Acc./Dec. time after Stall Prevention function is triggered. In addition, the acceleration and deceleration time will be extended depending on the Stall Prevention duration. If faster acceleration and deceleration are required, install proper braking options or use a higher rating motor and AC drive.
1.3.3 General Handling
1.3.3.1 Wiring
Connecting power supply to output terminals U/T1, V/T2 and W/T3 will damage the drive.
Check all the connections and wiring sequence before turning on the power. Failure to comply could cause drive damage.
1.3.3.2 Maintenance
9
Capacitors in the drive may still be charged for a short time after shutting off the power. Wait for the amount of time specified on the drive before any maintenance. Failure to comply could cause electrical shocks to personnel. Besides, do not touch the heatsink which can be very hot during operation. Replace the cooling fan only when the heatsink has cooled down after shutting off the power. In addition, when a synchronous motor is coasting to stop, it regenerates voltage to keep the drive terminals live even when the drive power is off. Wait until the motor is fully stopped before drive maintenance. Failure to comply could cause electrical shocks to personnel.
1.3.3.3 Wiring Tools
Use only the tools suggested by the terminal supplier during drive maintenance.

EVO6000 complies with the European LVD standard EN 61800-5-1 (2007) reducing the current leakage to below 10mA DC under testing condition regulated by IEC 60990
(1999).
24
Follow the instructions below to remove the jumper if an even lower current leakage to a even lower level.
Removing the jumper may increase the signal interference.
1. Front right corner of the machine, remove the screw using a screwdriver.
2. Remove the top right corner of the right side of the ground blade screw and save.
4.2.3 Main Circuit Cable Size and Tightening Torque
Select the cables and crimp terminals according to Table 4.2.2.
1. The recommended cables (copper conductors) are 600 V vinyl-sheathed cables which has
25
continuous temperature tolerance up to 75°C with ambient temperature tolerance up to 40 °C and wiring distance up to 100 meters.
2. Terminal + and - are only for connecting DC reactor and braking resistor options. Do not connect it to other devices.
3. Consider the amount of voltage drop when selecting cable sizes. Increase the cable size when the voltage drop exceeds 2% of the motor rated voltage. The amount of voltage drop can be calculated using the following formula:
Line drop voltage (V) = 3 × cable resistance (Ω/km) × cable length (m) × current (A) × 10 -3

Default

PID control utilizes Proportional, Integral and Derivative Control to minimize the deviation between the PID target and feedback.
■ P Control
P control outputs the proportion of P gain and the deviation linearly. With only P control, the deviation will not fall to 0.
■ I Control
I control outputs the integral of the deviation. This minimizes the deviation between the PID target and feedback but not suitable for rapid load fluctuations.
■ D Control
D control multiplies a time constant with deviation derivative (deviation slope) to predict the deviation, and then adds this value to the PID input. This utilizes derivative to control the braking and vibration.
D control tends to cause instability as the interference to deviation signal is larger. Use P control only when necessary.
■ PID Control Operation
See the PID operation illustrated below how the P, I and D output frequency changes when the deviation between the PID target and feedback is constant.
■ PID Control Applications
PID control can be used in the following applications.
Application
Speed
Control
Pressure
Description
Adjusts the machinery speed to the target speed.
Synchronizes the machinery speed from other machinery as the target speed.

■ PID Target Input Methods
The PID target can be input according to the methods showed in Table 6.6. If more than one
PID targets are input, it will be selected as per the priority.
Ex. When E3-01=9 (PID Target) and E5-00=2 (PID Target), the signal from terminal A1 will be selected as the PID target.

Note: When both terminal A1 and A2 are set to 9 (PID Target), oPE07 fault will be triggered.
■ PID Feedback Input Methods
There are two input methods. The first is to input one feedback signal for normal PID control.
The second is to input two signals to control the deviation in between.
Normal PID Feedback:
Selects the PID feedback signal in the source listed in Table 6.7.

The drive calculates the voltage loss on the output side using the output voltage and the d2-04 (Motor Line-to-Line Resistance) value, and improves the torque when it is insufficient during start or running at low speed.
Compensation voltage=Motor primary voltage loss x C3-00.
□ Torque Compensation in Sensorless Voltage Vector Control (SVVC)
72
The motor excitation currents d-axis and q-axis are controlled separately. Torque compensation affects q-axis current only.
Compensation voltage= q-axis voltage compensation (calculated by q-axis current) x C3-00
Adjustment:
Normally there is no need to change this parameter setting. However, adjust this setting by scaling of 0.05 in the following situations.
· Increase the setting when using a long motor cable
· Decrease the setting when the motor oscillates
· During running at low speed, adjust C3-00 to keep the output current below the drive rated current
Note:
· Do not change the setting in Sensorless Voltage Vector Control as it will reduce the torque accuracy.

WARNING!
Safety during Machinery Restart
·
·
Make sure wiring for Run/ Stop and safety circuits are correct and check if the machinery is normal after applying power to the drive. Improper wiring could cause inquiry due to machinery sudden movement. When setting 3-wire sequence control, the drive could suddenly start running due to the control circuit momentarily close.
If the Run command is active at power up with 3-wire sequence wiring and 2-wire sequence setting (default), the motor will run in reverse direction at power up. To avoid this, set b1-10 (Run Command at Power up)=0
(Ignore) to ignore an active Run command at power up.

If the input terminal assigned to FJOG command is closed, the drive runs in forward direction at the frequency set to L1-16. The RJOG command also causes the same action in reverse direction.
The FJOG and RJOG command can be set independently.
Note:
·
·
The FJOG/ RJOG command overrides all other frequency commands. However, RJOG command is disabled when b1-03= 1 (Reverse Rotation Disabled).
Entering both the FJOG and RJOG commands simultaneously for 500 ms or longer will trigger an alarm and the drive will ramp to stop.

P3 Stall Prevention
When the load is too heavy or the deceleration time is too short, the motor may not be able to keep up with the frequency command and slips. The regenerative power from the power will then exceed the tolerance of main circuit capacitor and trigger an ov (Overvoltage) fault to stop the drive. This process is called “stall”. When a motor stalls, it cannot be accelerated or decelerated. The Stall Prevention Function prevents the motor from stalling and while allowing
128
the motor to keep up with the desired speed without changing the acceleration or deceleration times. This function can be set separately for acceleration, operating at constant speeds, and deceleration.

Chapter 7│Options
The following peripheral device options can be installed to improve the drive performance.
Contact the local distributor to purchase the options if needed.
7.1 AC Reactor Option
7.1.1 Installing an AC Reactor
The non-linear components such as rectifiers and SCRs on the drive input side will cause high harmonic input current which interrupts the power supply and affects the power factor. To suppress the surges in currrent and improve the power factor, install an AC reactor on the drive input side in the following situations.
To suppress harmonic current or improve the power factor of the power supply
To suppress voltge surges on the input power when using a phase advancing capacitor switch so as to protect the connected devices.
A large capacity power transformer (600kVA and above) is connected to the drive.
Note: Always install an AC reactor when connecting a SCR such as a DC drive to the same power supply regardless of the power supply conditions.

11.5 Message Format
11.5.1 Message Content
In Modbus communications, the master gives commands to the slave, and the slave responds.
The following table shows the configured message for both sending and receiving, and the length of data packets is determined by the command (function) content.
11.5.2 Message Configuration

Function code: 8-bit binary
Data Characters: n×8-bit data, n<=16
CRC checksum:
16-bit, consists of 2 sets of 8-bit binary
Retain no signal input ≧10 ms
11.5.3 Slave Station Address
Use code between 0 and FF (hex) to set the slave station address. If a message with slave station address 0 is sent (broadcast), the command from the master will be sent to all slaves.
The slave do not responds to a broadcast message.
00H: To all drive (broadcast)
01H: To drive address 01
0FH: To drive address 15
10H: To drive address 16, so on and so forth up to 31( 1FH).
11.5.4 Function Code
There are four types of function codes:
03H : Read Modbus registers
06H : Write a word to registers(Write to registers)
08H : Loopback test
10H : Write to multiple registers
11.5.5 Data
By combining the Modbus register address (test code in case of a loopback test) and the
180
register data, the drive configures consecutive data. The length of the data depends on the command details.
The Modbus register always consists of a data length of two bytes. Data written into the register must also consist of a length of two bytes. Register data read out from the drive will always have two bytes.
11.5.6 Error Check
The drive check data validity using CRC scheme.
11.5.7 Command Data
When the drive receives data, it checks for errors. To do so, the drive calculates the CRC and compares it to the CRC-16 value received in the message. The command will not be processed if these two values do not match.
Use the default value of FFFFH (i.e., all 16 bits equal 1) to caculate CRC-16 in Modbus. Calculate the CRC-16 checksum using the following steps:
(1).
(2).
The starting value of a 16-bit register value is FFFFH (all 16 bits equal 1).
Perform an exclusive OR of this value and the slave address. Then save the result in
(3).
the register.
Right shift the result, put 0 to the left of the high-order byte and check the CRC
(4).
register value.
If the value is 0, save the result from step (3) above in the CRC register.
If the value is not 0, perform an exclusive OR of the result from stop (3) and the value
A001h(1010 0000 0000 0001). Then save the result in the CRC register.
(5).
(6).
Repeat step (3) and (4) until 8-bit operations are all performed.
Repeat step (2) to (5). Recive next 8-bit command data until all the command data are caculated. The result of the last shift is the CRC checksum. Send the low-order byte before the high-order byte when sending the CRC checksum. For an example of
CRC checksum 1241hex, the high-order byte of CRC-16 must be set to 41hex, and the low-order byte must be set to 12hex.
CRC Calculation:
UWORD ch_sum ( UBYTE long , UBYTE *rxdbuff ) {
BYTE i = 0;
UWORD wkg = 0xFFFF;
while ( long-- ) {
wkg ^= rxdbuff++;
for ( i = 0 ; i < 8; i++ ) {
181
if ( wkg & 0x0001 ) {
wkg = ( wkg >> 1 ) ^ 0xa001;
}
else {
wkg = wkg >> 1;
}
}
}
}
return( wkg );
11.5.8 Response Message
Perform a CRC calculation on the response message according to the above description. The result of the calculation should match the CRC checksum of the response message.
11.6 Example of Reading / Responding Data

When a communications error (overrun, framing, parity, or CRC) is detected in the command message.
The slave address in the command message do not match the slave address in the drive
(Set the slave address for the drive using E6-06 in advance).
The gap between two blocks of a message is greater than 24 bits.
The command message length is incorrect.
Note: When the slave address in the command message is 00H, all slaves perform the write function, but do not send any response message to the master.
