Set frequency is <0.1Hz. Increase set frequency
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.
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.
The VSD will decelerate to stop and flashes E.S. when there is
an external emergency stop signal via the multi-function input
terminals (see descriptions of [521] to [524]).
The VSD stops immediately and then flashes b.b. when exter-
nal base block is input through the multi-functional input termi-
nal (see descriptions of [521] to [524])
PID feedback signal circuit error detection
1. When REMOTE KEYPAD does not connect with VSD, this sig-
nal will be displayed on the Remote keypad.
2. When REMOTE KEYPAD connects with VSD, this signal will
be displayed on the main keypad.
3. When both REMOTE KEYPAD and main KEYPAD display this
signal means communication errors
