Minimum motor speed, ramp-up and ramp-down time (P1080)
• Set the minimum motor speed under parameter MIN RPM
• Press OK (parameter MIN RPM)
• Change the value by pressing UP or DOWN
• Press OK to confirm
• Set the ramp-up time under parameter RAMP UP for the
• Set the ramp-down time under parameter RAMP DWN for the
The values are displayed in seconds. In both cases, the times indicated
should not be too short, as this might result in an alarm. The ramp
times are only valid in normal operation. If the drive uses PID control,
the PID specific settings have priority. An example for a PID setup is
provided in Chapter -> Starter.

G120P requires the minimum
speed to be set in rpm and not in
Hz. You can use the "Frequency
converter"-App available for
iPhone and Android to convert
Hz into rpm for your motor. The
minimum speed must be entered
as a fraction of the synchronous
motor speed if V/f control is
selected.
