Setting of switches AS1-5 to AS1-8
The function of switches AS1-5 to AS1-8 are described in Table 4-2.
Switch Function
AS1-5 Not Used
AS1-6 Hold-Position Hold-Position is active.
AS1-7 Offset Tuning Automatic Offset Tuning is
AS1-8 Enable
Hold-Position OFF allows normal operation.
ON causes the motor to quickly decelerate to rest and maintain a constant position
(in current or velocity modes). (Time to max velocity = 0 with the Hold function.)
Offset Tuning OFF allows normal operation.
ON causes Offset Tuning to automatically start the next time Enable is changed
from ON to OFF. The purpose of Offset Tuning is to remove DC offset voltages (on
the command input X3-1 and X3-2) and achieve a stationary motor shaft with
0VDC at the command input. Leave this switch OFF when not in use. See Figure
4-1 for additional information.
Enable OFF disables the control and the motor coasts to a stop.
ON allows normal operation.
Note: AS1-8 and X3-9 must both be enabled to allow control operation.
