Fail to start directly
1.If the VSD is set to external control mode ([213]=001), and
direct start is disabled ([335]=001), the VSD cannot be started
and will flash STP1 when the Run switch is ON when applying
power (see descriptions of [335]).
2.Direct start is possible when [335]=000.
Keypad emer-
gency stop
1. If the VSD is set to external control mode ([213]=001), the
VSD will stop according to the setting of [337] when the stop
key is pressed. STP2 flashes after stop. Turn the Run switch to
OFF and then ON again to restart the VSD.
2. If the VSD is in communication mode and Stop key is ena-
bled, the VSD will stop in the way set by [337] when Stop key is
pressed during operation and then flashes STP2. The PC has to
send a Stop command then a Run command to the VSD for it to
be restarted.
