Table 22: Parameters (cont'd.)
Parameter Default Description
Decel Seconds 5 Seconds Time in seconds for the drive to
ramp down from Max Frequency
to 0 Hz.
For ESP applications,
maximum recommended Decel
Seconds is 10.0.
Forward/Reverse Run Forward Direction of Motor Rotation.
V/F Curve Select 60Hz Std Torque Select 1 of 6 preset V/F curves.
These include Standard, Medium,
and High Torque settings for 50Hz
and 60 Hz operation. Standard
torque is default. Use medium
or high torque when faced with
a hard starting motor. Medium
and high torque settings apply a
voltage boost to the V/F curve at
low frequencies. This parameter
may NOT be changed while the
drive is running.
V/F CurveVBias 0.0 Volts Applies a voltage bias to the
drive’s V/F curve AT MAX
FREQUENCY. The bias is linearly
interpolated at frequencies less
than Max Frequency.
DriveMaxVolts 480 Volts Drive voltage output at Max
Frequency. This parameter may
NOT be changed while the drive
is running.
