● OFF3
– Switch to speed-controlled operation
– n_set = 0 is input immediately to brake the drive along the OFF3 deceleration ramp
(p1135).
– When standstill is detected, the motor brake (if parameterized) is closed.
– The pulses are suppressed when the motor brake application time (p1217) has
elapsed. Standstill is detected when the actual speed value is less than the speed
threshold (p1226) or when the monitoring time (p1227) that started when speed
setpoint ≤ speed threshold (p1226) has expired.
– Switching-on inhibited is activated.
Parameterization with STARTER
The "Torque setpoint" parameter screen is selected with the icon in the toolbar of the
STARTER commissioning tool.
