7.4 Fixed frequency setpoint values
DC1 variable frequency drive 12/13 MN04020003Z-EN www.eaton.com 125
Figure 77: Example: Activation of the fixed frequencies with acceleration and deceleration
ramps
The change between the individual fixed frequencies is done with the accel-
eration times and deceleration times set at P-03 and P-04. ( Figure 77).
When the FWD or REV enables are revoked, the output frequency is inhib-
ited directly (coasting to halt).When P-05 = 0, the drive performs a
controlled deceleration .
7.4.2 Frequency jump
In systems with mechanical resonances, you can skip this frequency range
for stationary operation.
