Direction can be confirmed by
rotating the shaft clockwise as
viewed from the back, where,
after 90 degrees of rotation
the cos will now be in phase
with the excitation frequency
and the sin signal will be null.

Servomotor Information:
NOTE:
See servomotor specifications in IMA-S catalog 2700-4014
NOTE:
Do NOT exceed 650Vdc or 365 Vdc depending on motor selected, as it may cause
damage to the actuator.
Supplying the motor more than 10% of the rated motor voltage may increase the rotational speed of
the motor greater than its specified maximum speed, leading to premature failure of the actuator

Don't exceed rated motor voltage.
Earth Grounds/Shielding: The green wire or green wire with yellow stripe is the internal grounding
terminal and shall be used as the equipment grounding means.
*Brake Information: 24 Vdc power is required to release the brake during operation. A brown and
white 20AWG lead exit the conduit opening as a pair and are used for brake wires. Ensure that these
two wires are used for the brake.
NOTE:
The holding brake must be wired such that the servomotor will not turn unless 24V
power is supplied to the brake. This ensures that the brake is released prior to spinning the motor.
5 .3 .2 Feedback Wiring
The wiring of the feedback device is critical to the operation of the actuator with the selected servo
drive. The installer must not pull or tug on the encoder and brake wires when cutting, stripping and
terminating as it may damage the small gauge wires which will prevent the actuator from operating.
NOTE:
Refer to Servo Drive User Manual for wiring instructions.
