4 SERVOPACK Specifications and Dimensional Drawings

4.1.3 SERVOPACK Ratings and Specifications

4-4

* 1. Use the SERVOPACK within the ambient 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. The forward direction indicates the direction in which the linear scale counts up (Phase-A advance).
* 4. The built-in open collector power supply is not electrically insulated from the control circuit in the

SERVOPACK.

* 5. The DC reactor connection terminals for power supplies designed for minimum harmonics are not

included in SERVOPACKs with capacities of 7.5 kW.
