4.1 SERVOPACK Ratings and Specifications
4-5
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.

Sequence Input Signal allocation can
be modified. Servo ON, P control (or Control mode switching, forward/reverse motor
movement by internal speed setting, zero clamping, reference pulse pro-
hibited), forward run prohibited (P-OT), reverse run prohibited (N-OT),
alarm reset, forward current limit, and reverse current limit (or internal
speed selection)
Sequence Output Fixed Output Servo alarm, 3-bit alarm codes
Signal allocation can
be modified. Positioning completed (speed coincidence), during servomotor move-
ment, servo ready, during current limiting, during speed limiting, brake
released, warning, selecting three of the NEAR signals.

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.
