Built-in Open-Collector Power
Supply***
+12 V (1 kΩ built-in resistor)
* 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.
** Forward is clockwise viewed from the non-load side of the servomotor, (counterclockwise viewed from the load and
shaft end).
***The built-in open collector power supply is not electrically isolated from the control circuit in the servo amplifier.
