*
1
The power voltage must not exceed 230 V + 10% (253 V). If it is likely to exceed this
limit, use a step-down transformer.
*
2
The ambient temperature must be within the specified range. Even if the SERVO-
PACK is installed in a box, the temperature inside the box must not exceed the range.
*
3
Speed regulation can be calculated using the following formula:
Speed regulation =
(no-load motor speed – full-load motor speed)
rated motor speed
× 100%
Under actual operating conditions, voltage or temperature fluctuation causes drift
to the amplifier or changes the operating resistance, resulting in the motor speed
being changed.
The percentage of the motor speed change to the rated motor speed is called
“speed regulation”.
*
4
Forward rotation is defined as the clockwise rotation when viewed from the motor on
the opposite side of the load. (It is the counterclockwise rotation when viewed from
the load or shaft.)
*
5
Built-in open collector power supply is not electrically isolated from the control circuit
inside the SERVOPACK.
*
6
For 1:1 communication, set the rotary switch to “0”.
