P2-20 Standby Mode
0.0: Disabled
0.1 to 60.0
Seconds 0.0
When P2-20 >0, the drive enters
standby mode if the minimum
speed is maintained for the time
period set in P2-20.
Note: P2-16 must be set to zero
for standby mode to operate.
P2-21

Factor
0.000 to 30.000 - 0.000
Disabled if P2-21 is set to 0.
If P2-21 is set >0, the variable
selected in P2-22 is multiplied
by the factor entered in P2-21,
and displayed while the drive is
running.

Effective power stage switching
frequency. Higher frequencies
reduce the audible ‘ringing’ noise
from the motor, and improve
the output current waveform, at
the expense of increased drive
losses.
