If the motor fails to start when the ON command has been given:
Ø Check that P0010 = 0.
Ø Check that a valid ON signal is present.
Ø Check that P0700 = 2 (for digital input control) or
P0700 = 1 (for OP control).
Ø Check that the setpoint is present (0 to 10V on Terminal 7) or the setpoint has
been entered into the correct parameter, depending upon the setpoint sourc e

the defined setpoint by analogue input.
