4. Push the fuse holder back into the power entry module with the same
orientation you observed in step 2.
5. Close the hinged cover.
Changing the Line Voltage
Follow these steps to change the line voltage on your MID-7654/7652:
1. Pry open the hinged cover on the power entry module (number 7 in
Figure 6).
2. Remove the fuse holder.
3. Replace the two fuses with the appropriate fuses for the desired line
voltage as listed in the Specifications section.
4. Rotate the fuse holder 180 degrees so the desired line voltage number
shows through the window when the power module cover is closed.
5. Push the fuse holder back into the power entry module with the new
orientation.
6. Close the hinged cover.
Amplifier/Driver Command Signals
The PWM amplifiers used in the MID-7654/7652 accept an
industry-standard ±10 V analog torque (current) command signal. Servo
motion controllers used with the MID-7654/7652 provide this standard
output and are programmed to close both the velocity loop and position
loop using an enhanced PID algorithm.
Specifications
The following specifications apply only to the MID-7654/7652. You must
account for your motion controller to obtain a system specification. Refer
to your controller specifications to determine overall system specifications.
Some signals define compatibility as signal pass-through, which means the
MID-7654/7652 may use passive filtering on these signals. This will not
affect the voltage range or currenthandling capability. Consult your motion
controller specifications to determine the allowable voltage range and logic
level compatibility of the signal.
