4.3.1.2.4 Fault reaction properties
The behavior of the fault reaction can be influenced via object pn62.
Fault reaction properties
Properties of the fault reaction
The meaning of the single bits in pn62 is defined as follows:
fault reaction properties
Source for the starting speed of the deceleration ramp
0: Setpoint speed (output ramp generator)
1: Actual speed
4.3.1.2.5 Error reaction/stop_function torque limit
Another (higher) torque limit is required in some applications for the state Fault re-
action active.
It is often requested to decelerate with maximum torque (e.g. at the limiting charac-
teristic), then to reduce the torque to a small residual value during the standstill
phase (e.g. in order to relieve a shaft) before the modulation is then switched off.
Which torque limit shall be active during fault reaction can be selected in co61 Bit
0...5.
