Ø
Check if P0700 = 2 (for digital input control) or
Ø
P0700 = 1 (for BOP control).
Check if the correct setpoint is available (0 to 10 V on terminal 3), or if the setpoint
Ø
was entered in the correct location in dependence of the setpoint source (P1000).
Refer to the parameter list for more detailed information.
If the motor does not start after changing the parameters, set P0010 = 30 and then
P0970 = 1, and press P to reset the variable speed drive to the factory-set parameter
default values.
Use a switch between terminals 5 and 8 on the control terminal bar. The drive
should now run according to the default setpoint at the analog input.
