Application Examples
If the frequency converter is at the torque limit and a stop
command is activated, terminal 29 Output (programmed to
Torque limit and stop [27]) is activated. The signal to
terminal 27 changes from 'logic 1' to 'logic 0', and the
motor starts to coast, thereby ensuring that the hoist stops
even if the frequency converter itself cannot handle the
required torque (i.e. due to excessive overload).
