4 SERVOPACK Specifications and Dimensional Drawings
4.1.3 SERVOPACK Ratings and Specifications
4-4
* 1. Use the SERVOPACK within the surrounding air temperature range. When enclosed in a control
panel, internal temperatures must not exceed the ambient temperature range.
* 2. 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 represent speed
regulation due to voltage and temperature variations.
* 3. Forward is clockwise viewed from the non-load side of the servomotor. (Counterclockwise viewed
from the load and shaft end)
* 4. The built-in open collector power supply is not electrically insulated from the control circuit in the
SERVOPACK.
Internal
Func-
tions Dynamic Brake Operated at main power OFF, servo alarm, servo OFF or overtravel.
Overtravel Stop Dynamic brake stop at P-OT or N-OT, deceleration to a stop, or coast to a
stop
Electronic Gear 0.01 ≤ B/A ≤ 100
Protection Overcurrent, overvoltage, low voltage, overload, regeneration error, main
circuit detection section error, heat sink overheated, no power supply,
overflow, overspeed, encoder error, overrun, CPU error, parameter error
