WARNING:

Caution:

Do not touch any circuit board, power device or electrical connection before you first ensure that power has been disconnected and there is no high voltage present from this equipment or other equipment to which it is connected. Electrical shock can cause serious or fatal injury.

Be sure that you are completely familiar with the safe operation of this equipment. This equipment may be connected to other machines that have rotating parts or parts that are controlled by this equipment. Improper use can cause serious or fatal injury.

Be sure all wiring complies with the National Electrical Code and all regional and local codes or CE Compliance. Improper wiring may cause a hazardous condition.

Be sure the system is properly grounded before applying power. Do not apply AC power before you ensure that grounds are connected. Electrical shock can cause serious or fatal injury.

Do not remove cover for at least five (5) minutes after AC power is disconnected to allow capacitors to discharge. Electrical shock can cause serious or fatal injury.

Improper operation of control may cause violent motion of the motor shaft and driven equipment. Be certain that unexpected motor shaft movement will not cause injury to personnel or damage to equipment. Peak torque of several times the rated motor torque can occur during control failure.

Motor circuit may have high voltage present whenever AC power is applied, even when motor is not rotating. Electrical shock can cause serious or fatal injury.

If a motor is driven mechanically, it may generate hazardous voltages that are conducted to its power input terminals. The enclosure must be grounded to prevent a possible shock hazard.

When operating a motor with no load coupled to its shaft, remove the shaft key to prevent injury if it were to fly out when the shaft rotates.

The motor shaft will rotate during the autotune procedure. Be certain that unexpected motor shaft movement will not cause injury to personnel or damage to equipment.

A DB Resistor may generate enough heat to ignite combustible materials. To avoid fire hazard, keep all combustible materials and flammable vapors away from brake resistors.

The user must provide an external hard-wired emergency stop circuit to disable the control in the event of an emergency.

Suitable for use on a circuit capable of delivering not more than the RMS symmetrical short circuit amperes listed here at rated voltage.

MN1202 General Information 1-3

Caution:

Avoid locating control immediately above or beside heat generating equipment, or directly below water or steam pipes.

Avoid locating control in the vicinity of corrosive substances or vapors, metal particles and dust.

For UL installations, do not connect any resolver cable shields to the motor frame. At a minimum, resolver signal integrity will be compromised and damage to the control may result.

For CE installations, refer to CE guidelines stated in Sections 3 and 7 of this manual.

Do not connect AC power to the control terminals U, V and W. Connecting AC power to these terminals may result in damage to the control.

Baldor recommends not using “Grounded Leg Delta” transformer power leads that may create ground loops and degrade system performance. Instead, we recommend using a four wire Wye.

Logic signals are interruptible signals; these signals are removed when power is removed from the drive.

Controls are intended to be connected to a permanent main power source, not a portable power source. Suitable fusing and circuit protection devices are required.

The safe integration of the drive into a machine system is the responsibility of the machine designer. Be sure to comply with the local safety requirements at the place where the machine is to be used. In Europe this is the Machinery Directive, the ElectroMagnetic

Compatibility Directive and the Low Voltage Directive. In the United States this is the

National Electrical code and local codes.

Controls must be installed inside an electrical cabinet that provides environmental control and protection. Installation information for the drive is provided in this manual. Motors and controlling devices that connect to the drive should have specifications compatible to the drive.

Violent jamming (stopping) of the motor shaft during operation may damage the motor and control.

Do not tin (solder) exposed wires. Solder contracts over time and may cause loose connections.

Electrical components can be damaged by static electricity. Use ESD (electro-static discharge) procedures when handling this control.

Ensure that resolver or encoder wires are properly connected. Incorrect installation may result in improper rotation or incorrect commutation.

The holes in the top and bottom of the enclosure are for cable clamps. Be sure to use an M4 bolt 12mm in length. Longer bolts may short circuit the electrical components inside the control.

Section 3 Installation

Receiving & Inspection

Baldor Controls are thoroughly tested at the factory and carefully packaged for shipment.

When you receive your control, there are several things you should do immediately.

Observe the condition of the shipping container and report any damage immediately to the commercial carrier that delivered your control.

Remove the control from the shipping container and remove all packing materials. The container and packing materials may be retained for future shipment.

Verify that the part number of the control you received is the same as the part number listed on your purchase order.

Inspect the control for external physical damage that may have been sustained during shipment and report any damage immediately to the commercial carrier that delivered your control.

If the control is to be stored for several weeks before use, be sure that it is stored in a location that conforms to published storage humidity and temperature specifications stated in this manual.

Location Considerations

The location of the control is important. Installation should be in an area that is protected from direct sunlight, corrosives, harmful gases or liquids, dust, metallic particles, and vibration. Exposure to these can reduce the operating life and degrade performance of the control.

Several other factors should be carefully evaluated when selecting a location for installation:

For effective cooling and maintenance, the control should be mounted on a smooth, non-flammable vertical surface.

At least 0.6 inches (15mm) top and bottom clearance must be provided for air flow. Refer to Section 6 for mounting dimensions.

Altitude derating. Up to 3300 feet (1000 meters) no derating required. Derate the continuous and peak output current by 1.1% for each 330 feet (100 meters) above 3300 feet.

Temperature derating. From 5

C to 45

C ambient no derating required.

Above 45

C, derate the continuous and peak output current by 2.9% per

C above 45

C. Maximum ambient is 55

Mechanical Installation

Mount the control to the mounting surface. The control must be securely fastened to the mounting surface by the control mounting holes. The location of the mounting holes is shown in Section 6 of this manual.

Electrical Installation

All interconnection wires between the control, AC power source, motor, host control and any operator interface stations should be in metal conduits. Use listed closed loop connectors that are of appropriate size for wire gauge being used. Connectors are to be installed using crimp tool specified by the manufacturer of the connector. Only class 1 wiring should be used.

System Grounding Baldor controls are designed to be powered from standard single and three phase lines that are electrically symmetrical with respect to ground. System grounding is an important step in the overall installation to prevent problems. The recommended grounding method is shown in Figure 3-1 for UL compliant systems (Figure 3-2 for CE compliant systems).

System Grounding

Continued

Ungrounded Distribution System

With an ungrounded power distribution system it is possible to have a continuous current path to ground through the MOV devices. To avoid equipment damage, an isolation transformer with a grounded secondary is recommended. This provides three phase AC power that is symmetrical with respect to ground.

Input Power Conditioning

Baldor controls are designed for direct connection to standard single and three phase lines that are electrically symmetrical with respect to ground. Certain power line conditions must be avoided. An

AC line reactor or an isolation transformer may be required for some power conditions.

•

If the feeder or branch circuit that provides power to the control has permanently connected power factor correction capacitors, an input AC line reactor or an isolation transformer must be connected between the power factor correction capacitors and the control.

•

If the feeder or branch circuit that provides power to the control has power factor correction capacitors that are switched on line and off line, the capacitors must not be switched while the control is connected to the AC power line. If the capacitors are switched on line while the control is still connected to the AC power line, additional protection is required. TVSS

(Transient Voltage Surge Suppressor) of the proper rating must be installed between the AC line reactor or an isolation transformer and the AC input to the control.

Power Disconnect

A power disconnect should be installed between the input power service and the control for a fail–safe method to disconnect power. The control will remain in a powered-up condition until all input power is removed from the control and the internal bus voltage is depleted.

Protection Devices

The control must have a suitable input power protection device installed. Input and output wire size is based on the use of copper conductor wire rated at 75

C. Table 3-1 describes the wire size to be used for power connections and the ratings of the protection devices.

Internal Power Requires External Power

Dynamic Brake Resistor An external DB (dynamic brake or regen resistor) resistor is required to dissipate excess power from the DC bus during motor deceleration operations. An external 320 watt resistor must be connected at the X7 terminals R1 and R2.

Refer to Section 6 for selection information or contact Baldor.

24VDC Logic Power If the control is equipped with the internal 24VDC logic power circuit (BSC1XXX–24–X),

24VDC may be connected to this input to maintain voltage on the logic circuits at all times. An external 24VDC (20V to 60V source) supply must be used. This supply must remain on when AC power to the control is disconnected. Connect the power supply leads to X7 input terminals +24V and 0V.

Note: All units are marked 24V and 0V. Do not connect an external 24VDC source to these terminals unless the control is equipped with the internal 24VDC logic power circuit (BSC1XXX–24–X).

Before you apply power, it is very important to verify the following:

Disconnect the load from the motor shaft until instructed to apply a load. If this cannot be done, disconnect the motor wires at X7-U, V and W.

Verify that switches are set correctly.

Verify the AC line voltage at the source matches the control rated voltage.

Inspect all power connections for accuracy, workmanship and tightness.

Verify that all wiring conforms to applicable codes.

Verify that the control and motor are properly grounded to earth ground.

Check all signal wiring for accuracy.

If using a transformer, switch the primary side only, and check that the secondary voltage is 115 VAC for single phase units and between 115 VAC and 230 VAC for three phase units.

Temporarily disconnect the input speed command signal (

10 VDC) from the

Control Signal Connector X2 inputs CMD + (pin 1) and CMD – (pin 2) and jumper the CMD + and CMD – inputs together.

Switch on the main power. The motor may run away “out of control” if the resolver wires are connected incorrectly. Turn power off immediately and check resolver wires. If the motor shaft rotates in the wrong direction, check the wiring of the motor and the resolver. Turn power on.

Verify that the “READY” LED is green, and the Status Monitor LED display on the front panel shows a decimal point on the bottom right. This verifies that power is applied, and the unit is enabled. If the motor is slowly rotating, adjust the Velocity Balance pot P4 for no rotation.

Adjust P6 Peak Current CW (clockwise), and verify that the motor has holding torque. If the motor has no holding torque, make sure that the Identity Module is fully inserted, and check the wiring of the Control Signal Connector X2 pins:

CW limit (pin 11), CCW limit (pin 12), ENABLE (pin 9), EMStop (pin 10). If the motor runs away or if Error 5 or 7 is displayed on the Status Monitor, switch off the main power immediately and check the resolver and motor wiring.

Again, switch off the main power, and reconnect the input speed command signal (

10 VDC) to the CMD + and CMD – inputs. Switch on the main power and apply a small input speed command (5V or less is suggested). Positive command voltage will cause CW shaft rotation and negative command voltage will cause CCW (counterclockwise) shaft rotation.

Note: When using single ended input, positive voltage input to CMD + causes

CW shaft rotation, and positive voltage input to CMD – causes

CCW shaft rotation.

MN1202 Switch Setting and Start-Up 4-3

Adjustment Procedure

The following procedure yields proper potentiometer adjustment for optimum servo control operation. For best results, read the entire procedure before making adjustments.

Apply a signal input command between 0 and 10 VDC at the Control Signal

Connector X2 inputs CMD + (pin 1) and CMD – (pin 2). +5 VDC (for CW shaft rotation) or –5 VDC (for CCW shaft rotation) is suggested. If the motor shaft rotates in the wrong direction for a given polarity of the signal input voltage, check the wiring of the motor and resolver. If the shaft still rotates in the wrong direction, reverse the CMD + and CMD – inputs.

Note: When using single–ended input, positive voltage input to CMD + causes CW shaft rotation, and positive voltage input to CMD – causes CCW shaft rotation.

Slowly turn the Peak Current (P6) pot 1/4 turn CW, observing that the motor shaft speed may increase and stabilize.

If connected, verify that the CW and CCW limit switches properly inhibit the machine travel in the direction defined.

If the motor shaft drifts, or rotates when sent a zero velocity (“don’t move“) command, slowly adjust the Velocity Balance (P4) pot to eliminate any motor shaft rotation.

Note: The setting of potentiometers P1 and P3 must allow the control to reach the maximum velocity for the command input before P5 can be correctly adjusted.

Begin with both P1 and P3 set fully CW.

The adjustment of the Velocity Loop Gain (P5) pot may be accomplished by either of two methods: a.

Slowly turn the Velocity Loop Gain pot CW until the axis becomes unstable and then turn the pot back 1/8 turn CCW.

Using a step input command with an amplitude of 10% of full desired speed and a suggested duration of 1 second on/1 second off, adjust the

Velocity Loop Gain pot CW while monitoring the speed test point signal

(Control Signal Connector X2 pin 6) on a scope until the desired response is obtained. Refer to Figure 4-2 for typical responses.

Note: If the servo control is unstable at all pot settings there is probably a mechanical resonance.

If the motor shaft overshoots when stopping, turn the Tacho Gain (P3) pot CCW

CCW, being careful not to turn to full CCW. Full CCW on the Tacho Gain pot may cause the motor shaft speed to become uncontrollable.

The Input Gain (P1) pot can now be used to “fine tune” and optimize the maximum response for the given signal input voltage range. Note that steps 4 thru 6 may have to be repeated.

Section 5 Troubleshooting

Overview

The BSC Control requires very little maintenance and should provide years of trouble free operation when installed and applied correctly. Occasional visual inspection and cleaning should be considered to ensure tight wiring connections and to remove dust, dirt, or foreign debris which can reduce heat dissipation.

Operational failures called “Faults” will be displayed as they occur. A comprehensive list of these faults, their meaning and related information is provided in this section.

Before attempting to service this equipment, all input power should be removed to avoid the possibility of electrical shock. The servicing of this equipment should be handled by a qualified electrical service technician experienced in the area of high power electronics.

It is important to familiarize yourself with the following information before attempting any troubleshooting or service of the control. Most troubleshooting can be performed using only a digital voltmeter having an input impedance exceeding 1 megohm. In some cases, an oscilloscope with 5 MHZ minimum bandwidth may be useful. Before consulting the factory, check that all power and control wiring is correct and installed per the recommendations given in this manual.

Check that potentiometers P1 and P3 are set to allow the control to reach the maximum velocity for the command input.

Increase decel time or add a Regeneration Resistor.

Electrical Noise Considerations

All electronic devices are vulnerable to significant electronic interference signals

(commonly called “Electrical Noise”). At the lowest level, noise can cause intermittent operating errors or faults. From a circuit standpoint, 5 or 10 millivolts of noise may cause detrimental operation. For example, analog speed and torque inputs are often scaled at 5 to 10 VDC maximum with a typical resolution of one part in 1,000. Thus, noise of only 5 mV represents a substantial error.

At the extreme level, significant noise can cause damage to the drive. Therefore, it is advisable to prevent noise generation and to follow wiring practices that prevent noise generated by other devices from reaching sensitive circuits. In a control, such circuits include inputs for speed, torque, control logic, and speed and position feedback, plus outputs to some indicators and computers.

Relay and Contactor Coils Among the most common sources of noise is the coil of a contactor or a relay. When these highly inductive coil circuits are opened, transient conditions often generate spikes of several hundred volts in the control circuit. These spikes can induce several volts of noise in an adjacent wire that runs parallel to a control–circuit wire.

Figure 5-1 illustrates noise suppression for AC and DC operated coils.

EMC – Conformity and CE – Marking

The information contained herein is for your guidance only and does not guarantee that the installation will meet the requirements of the council directive 89/336/EEC.

The purpose of the EEC directives is to state a minimum technical requirement common to all the member states within the European Union. In turn, these minimum technical requirements are intended to enhance the levels of safety both directly and indirectly.

Council directive 89/336/EEC relating to Electro Magnetic Compliance (EMC) indicates that it is the responsibility of the system integrator to ensure that the entire system complies with all relative directives at the time of installing into service.

Motors and controls are used as components of a system, per the EMC directive. Hence all components, installation of the components, interconnection between components, and shielding and grounding of the system as a whole determines EMC compliance.

The CE mark does not inform the purchaser which directive the product complies with. It rests upon the manufacturer or his authorized representative to ensure the item in question complies fully with all the relative directives in force at the time of installing into service, in the same way as the system integrator previously mentioned. Remember, it is the instructions of installation and use, coupled with the product, that comply with the directive.

Wiring of Shielded (Screened) Cables

Remove the outer insulation to expose the overall screen.

Conductive

Clamp

MN1202 CE Guidelines 7-1

7-2 CE Guidelines

Using CE approved components will not guarantee a CE compliant system!

The components used in the drive, installation methods used, materials selected for interconnection of components are important.

The installation methods, interconnection materials, shielding, filtering and grounding of the system as a whole will determine CE compliance.

The responsibility of CE mark compliance rests entirely with the party who offers the end system for sale (such as an OEM or system integrator).

Baldor products which meet the EMC directive requirements are indicated with a “CE” mark. A duly signed CE declaration of conformity is available from Baldor.

EMC Wiring Technique

Capacitor

CABINET

The drawing shows an electroplated zinc coated enclosure, which is connected to ground.

This enclosure has the following advantages:

– All parts mounted on the back plane are connected to ground.

– All shield (screen) connections are connected to ground.

Within the cabinet there should be a spatial separation between power wiring (motor and AC power cables) and control wiring.

SCREEN CONNECTIONS

All connections between components must use shielded cables. The cable shields must be connected to the enclosure. Use conductive clamps to ensure good ground connection. With this technique, a good ground shield can be achieved.

EMC – FILTER

The EMI or main filter should be mounted next to the power supply (here BPS). For the connection to and from the main filter screened cables should be used. The cable screens should be connected to screen clamps on both sides. (Exception: Analog

Command Signal).

4 Grounding (Earth)

For safety reasons (VDE0160), all BALDOR components must be connected to ground with a separate wire. The diameter of the wire must be at minimum AWG#6 (10mm ).

Ground connections (dashed lines) must be made from the central ground to the regen resistor enclosure and from the central ground to the Shared Power Supply.

Y–CAPACITOR

The connection of the regeneration resistor can cause RFI (radio frequency interference) to be very high. To minimize RFI, a Y–capacitor is used. The capacitor should only be connected between the dynamic brake resistor housing and terminal pin

R1 (lead from Flex).

EMC Installation Instructions

To ensure electromagnetic compatibility (EMC), the following installation instructions should be completed. These steps help to reduce interference. Consider the following:

•

Grounding of all system elements to a central ground point

•

Shielding of all cables and signal wires

•

Filtering of power lines

A proper enclosure should have the following characteristics:

A) All metal conducting parts of the enclosure must be electrically connected to the back plane. These connections should be made with a grounding strap from each element to a central grounding point .

B) Keep the power wiring (motor and power cable) and control wiring separated. If these wires must cross, be sure they cross at 90 degrees to minimize noise due to induction.

C) The shield connections of the signal and power cables should be connected to the screen rails or clamps. The screen rails or clamps should be conductive clamps fastened to the cabinet.

D) The cable to the regeneration resistor must be shielded. The shield must be connected to ground at both ends.

E) The location of the AC mains filter has to be situated close to the drive so the

AC power wires are as short as possible.

F) Wires inside the enclosure should be placed as close as possible to conducting metal, cabinet walls and plates. It is advised to terminate unused wires to chassis ground.

G) To reduce ground current, use at least a 10mm 2 (6 AWG) solid wire for ground connections.

Grounding in general describes all metal parts which can be connected to a protective conductor, e.g. housing of cabinet, motor housing, etc. to a central ground point. This central ground point is then connected to the main plant (or building) ground.

Or run as twisted pair at minimum.
