Note: Speed regulation is defined as follows:
The motor speed may change due to voltage variations or amplifier drift and changes in
processing resistance due to temperature variation. The ratio of speed changes to the rated speed
represents speed regulation due to voltage and temperature variations.
*2
Forward is clockwise viewed from the non-load side of the servomotor, (counterclockwise
viewed from the load and shaft end).
*3
The built-in open collector power supply is not electrically isolated from the control circuit in the
servo amplifier.
