ZMR function (ZMR_HA): “Automatic” mode
When in “automatic” ZMR mode, the DS7-SWD soft starter will be ready to
be switched on immediately after the thermal motor image falls below the
100 % mark. “Automatic” ZMR mode is activated by setting the ZMR M/A
output bit (output byte 0, bit 3).
The illustration below shows the switching performance of soft starter
DS7-SWD on overload with the ZMR in Automatic mode.

DANGER
If the switch-on command for the DS7-SWD soft starter is sent
while in “automatic” ZMR mode, the motor will start up
automatically after the thermal motor image falls below the
100 % mark.
