7.1 ON/OFF Commands
The G120 inverter provides the following ON/OFF commands:
● ON / OFF (ON/OFF1)
● Coast stop (OFF2)
● Quick stop (OFF3)
Description
ON / OFF (ON/OFF1)
The ON/OFF1 function is an inter-coupled command. When the ON command is withdrawn,
then OFF1 is directly activated.
● Frequency setpoint = 0
The inverter ramps down to standstill in the period of time set in P1121.
● If parameterized, the motor holding brake is closed (P1215) when zero speed is detected.
When the brake application time (P1217) expires, the pulses are suppressed.
Zero speed is detected, if one of the following events occur:
– The actual speed drops below the Switch-off frequency (P2167).
– The monitoring time (P1227), started when the speed setpoint ≤ Switch-off frequency
(P2167), has expired.
Coast stop (OFF2)
● Instantaneous pulse suppression, the drive coasts to a standstill.
● If parameterized, the motor holding brake is closed immediately.
● Power-on inhibit is activated.
Before restarting, an OFF2 must be confirmed, e. g. via the key FN on the BOP. For
certain applications, it is useful to link the confirmation of an OFF2 or an OFF3 to the
ON/OFF function.
Note
If after a period of time, set in P1227, an OFF1 or an OFF3 has been unable to ramp
down the motor to Switch-off frequency (P2167), the system forces an immediate OFF2.
