2.6 Servomotor Compatibility

The MAC Series AC Brushless Servomotors provide exceptional performance

3.1 Motion Controller Installation

3.1.1 Receiving & Inspection

ORMEC Motion Controllers and their associated accessories are put through

rigorous tests at the factory before shipment. After unpacking, however, check

for damage which may have been sustained in transit. The bolts and screws

should all be tight, and motor output shafts should rotate freely by hand. Check

the motion controller and any of the accessories for bent or broken components

or any other physical damage before installing.

3.1.2 Panel Mounting & Environment

Panel mounting data is available in the Specifications Section and Appendix A.

The motion controller’s environment should be maintained as follows:

• Temperature should be between 0 and 55C.

• If the electrical panel is subjected to vibration, mount the unit on shock

absorbing material.

• Avoid use in corrosive atmospheres which may cause damage over time.

• Select a location with minimum exposure to oil, water, hot air, high

humidity, excessive dust or metallic particles.

• The proper mounting orientation for the motion controller is vertical on a

panel using the mounting holes (4) on the base plate.

3.1.3 Input Power - TB1

Motion Controllers are available to operate on either 115 VAC or 230 VAC

power (50/60 Hz). A servodrive control power output is provided at terminals r

and t which is interlocked with the integral switch/circuit-breaker on the top of

the unit. Use of this feature as illustrated in Appendix B eliminates the need

for additional switches and/or circuit breakers, and assures that servodrive

power will be disabled whenever power is removed from the Motion Controller.

To use this feature, the input voltage selected must match the voltage for

the selected servodrive’s control power. All ORMEC servodrives are

available with 230 VAC control power; some of the lower power E-Series are

also available with 115 VAC control power.

Input power connections are made on terminal block TB1, located on the top of

the unit. The label near TB1 indicates the input voltage of the unit. Copper

wire with an 80o

C temperature rating, 10 AWG maximum, is recommended for

terminal block TB1 wiring. The maximum terminal block screw torque is 5 inlbs. Connections to TB1 are described below:
