Motor holding torque on / off „DB“ (44h, 42h)
Prior to utilizing “DB” command to activate / deactivate the holding torque it must be enabled first in command
„m“ since otherwise command „DB“ remains ineffective.
Holding torque ever ON means that only motive shaft positioning operations are possible - either by aid of the
two keys provided or by a corresponding command via interface. The holding torque is automatically deactivated
as soon as the motor is getting a start command and is later autonomously re-enabled. Manual positioning
operations by hand cranks etc require deactivating the holding torque first by command “DB”.
Following modes are available::
Status Function
0 (30h) holding torque off
1 (31h) holding torque on
Example 1: Read current status (status = 0: no holding torque)

Response not confirmed
Note: If the holding torque is enabled (command „m“) the clamping is always active upon power on, reason why
holding torque OFF by command „DB0“ is only effective whilst device is under power supply.
