1-2 Quick Start MN760
WARNING: 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. Certain failure modes of the control can produce
peak torque of several times the rated motor torque.
WARNING: Dynamic brake resistors may generate enough heat to ignite combustible materials.
Keep all combustible materials and flammable vapors away from brake resistors.
WARNING: 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.
Caution: Disconnect motor leads (U, V and W) from control before you perform a “Dielectric
Withstand” test on the motor. Failure to disconnect motor from the control will result
in extensive damage to the control. The control is tested at the factory for high
voltage / leakage resistance as part of Underwriter Laboratory requirements.

4.1 Overview of Power Connections
The recommended grounding method is shown in Figure 4‐1.
Safety Ground - (G)
This is the safety ground for the drive that is required by code. One of these points must be connected to
adjacent building steel (girder, joist), a floor ground rod, or bus bar. Grounding points must comply with
national and local industrial safety regulations and/or electrical codes.

Motor Ground
The motor ground must be connected to one of the ground terminals on the drive.
Shield Termination
Either of the safety ground terminals located on the power terminal block provides a grounding point for
the motor cable shield. The motor cable shield connected to one of these terminals (drive end) should
also be connected to the motor frame (motor end). Use a shield terminating or EMI clamp to connect the
shield to the safety ground terminal. The NEMA 1/IP30 Kit may be used with a cable clamp for a
grounding point for the cable shield.
When shielded cable is used for control and signal wiring, the shield should be grounded at the drive end
only, never at both ends.
RFI Filter Grounding
Using single-phase drives with integral filter, or an external filter with any drive rating, may result in
relatively high ground leakage currents. Therefore, the filter must only be used in installations with
grounded AC supply systems and be permanently installed and solidly grounded (bonded) to the building
power distribution ground.
Ensure that the incoming supply neutral is solidly connected (bonded) to the same building power
distribution ground. Grounding must not rely on flexible cables and should not include any form of plug or
socket that would permit inadvertent disconnection. Some local codes may require redundant ground
connections. The integrity of all connections should be checked periodically.
4-2 Power Wiring MN761
4.2 Power Disconnect
A power disconnect should be installed between the input power service and the drive for a fail safe
method to disconnect power. The drive will remain in a powered‐up condition until all input power is
removed from the drive and the internal bus voltage is depleted.
4.3 Protective Devices
Recommended fuse sizes are based on the following:
115% of maximum continuous current for time delay.
150% of maximum continuous current for Fast or Very Fast action.
Note: These recommendations do not consider harmonic currents or ambient temperatures greater than
45°C.
Be sure a suitable input power protection device is installed. Use the recommended fuses and wire sizes

4.4 Electrical Installation
All interconnection wires between the drive, AC power source, motor, host control and any operator
interface stations should be in metal conduits or shielded cable must be used. 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.

4.4.1 Grounding Procedure
1. Remove covers. Cover removal is described in Chapter 3 of this manual.
2. Connect the power ground wire to the ground terminal G (see Figure 3‐2).
3. Connect the motor ground wire to the ground terminal G (see Figure 3‐2).
4.4.2 Motor Connections
All cables must be shielded and the shields must be grounded at the enclosure cable entrance.
1. Remove covers. Cover removal is described in Chapter 3 of this manual.
2. Connect the Motor leads to terminals U, V and W (see Figure 4‐2 for location).
Long Motor Leads
The wire leads that connect the motor to the control are critical in terms of sizing, shielding and the cable
characteristics. Short cable runs are usually trouble free but fault-monitoring circuitry can produce
numerous faults when long cables (over 100 feet) are used.
100+ ft (30m). Baldor recommends adding an optional load reactor to the output of the control.
250+ ft (75m). Baldor recommends adding an optional load reactor and common mode choke to the
control.
The load reactor and/or common mode choke should be placed in close physical proximity to the control.
Unexpected faults may occur due to excessive charging current required for motor cable capacitance.
If you use long motor leads and experience unexpected trips due to current overload conditions and are
not sure how to correctly size and connect the optional load reactors, please contact your Baldor
representative. Baldor is always glad to assist.
4.5 Optional Dynamic Brake Hardware
Refer to MN763DB for DB resistor connections.
Dynamic Brake (DB) Hardware must be installed on a flat, non‐flammable, vertical surface for effective
cooling and operation.

5.2 Control Input Connections
Determine if you will use NPN (factory setting) or PNP connections. NPN/PNP settings are shown in
Figure 5‐2. For NPN, CM (Common or ground) is used to switch the input signals. For PNP, P24
(+24VDC output) is used to switch the input signals.

1. For NPN Connections Connect the Digital Inputs to one pole of a switch and the other switch pole
to CM. An active low at P1 - P5 will activate the inputs.
For PNP Connections1 Connect the Digital Inputs to one pole of a switch and the other switch
pole to P24. An active High at P1 - P5 will activate the inputs.
2. The speed Command input can be wither a Voltage (0-10VDC) or a Current (0-20mA) input.
For Voltage input, either an external potentiometer or an external voltage reference can be used.
a. For an External reference voltage input, connect the 0-10VDC input to the VI terminal.
Connect the reference from the external source to the CM terminal.
b. For an external potentiometer, connect the pot as shown, one end to VR terminal, the wiper to
VI terminal and the other end to CM terminal.
For Current input, connect the 0-20mA source to the I terminal, the reference to CM terminal.
