DRIVE-06 Motor Rated Slip Value: 0.00-10.00 Hz Default: 1.0
Motor Rated Slip frequency, in Hertz, can be calculated using the following formula,
where “P” is equal to the number of poles.
Slip (Hz) =
(RPM
- RPM
)
120
sync nameplate
x Poles
NOTE: If the drive is connected to a synchronous motor (as selected in DRIVE-00),
the Motor Rated Slip value will be 0 Hz .
DRIVE-07 (40047) Reverse Enable Value: 0: Disabled
1: Enabled
Default: Disabled
When disabled, Reverse Enable prevents running of the motor in the reverse direction.
DRIVE-08 (40047) Starting Frequency Value: 0.00 – 10.00 Hz Default: 0.10
Starting Frequency determines the minimum frequency at the end of the deceleration,
where the motor is released.
Starting Frequency is also used to determine the minimum frequency at which the drive
will hold output until the ramp time expires in any programmed deceleration profile.
DRIVE-09 (44489) Minimum Frequency Value: 0.00 – 300.00 Hz Default: 0.00
Minimum Frequency defines the minimum speed setpoint that can be entered on the HMI
or by any plant controller.
DRIVE-10 (40046) Maximum Frequency Value: 1.00 – 300.00 Hz Default: 60.00
Maximum Frequency defines the highest frequency that the drive will generate. The Max-
imum Frequency value is also used (along with Ramp Time values) in the calculation of
acceleration and deceleration rates in both acceleration and deceleration profiles.
DRIVE-11 (40040)
Acceleration Ramp Time
Value: 0 – 1200 Seconds
Default: 120.0
Acceleration Ramp Time is the amount of time that it takes for the drive to reach the
maximum frequency when a Start command is received. Acceleration Ramp Time and
Maximum Frequency (DRIVE-10)
are used in the calculation of the acceleration rate in
the acceleration profile.
