Clamping torque
SD43510 $SA_FIXED_STOP_TORQUE (clamping torque)
Note
Clamping torque greater than 100%
A value for the clamping torque in SD43510 greater than 100% of the maximum motor torque
is only advisable for a short time. In addition, the maximum motor torque is limited by the drive.
For example, the following drive parameters have a limiting effect:
● p1520/p1521 upper torque limit/force limit / lower torque limit/force limit
● p1522/p1523 upper torque limit/force limit / lower torque limit/force limit
● p1530/p1531 power limit motorized / power limit regenerative
● p0640 current limit
● p0326 motor stall force correction factor

Monitoring window
SD43520 $SA_FIXED_STOP_WINDOW (monitoring window)
Default setting
The defaults for the setting data are set via the following machine data:
● Clamping torque:
● Monitoring window:
Effectiveness
The setting data for the clamping torque and monitoring window takes effect immediately. In
this way, the clamping state can be adapted to the machining situation at any time by the
operator or via the PLC user program.
