Table 25: Parameter Group 1 – Basic Parameters
Par. Description Minimum Maximum Default Units
P1-01 Maximum frequency / speed limit P1-02 500.0 50.0 (60.0) Hz / Rpm
Maximum output frequency or motor speed limit – Hz or rpm.
If P1-10 >0, the value entered / displayed is in Rpm.
P1-02 Minimum frequency / speed limit 0.0 P1-01 0.0 Hz / Rpm
Minimum speed limit – Hz or rpm.
If P1-10 >0, the value entered / displayed is in Rpm.
P1-03 Acceleration ramp time See Below 5.0 / 10.0 Seconds
Acceleration ramp time from 0 to base speed (P1-09) in seconds.
FS2 & FS3 : 5.0 Seconds Default Setting, 0.01 Seconds Resolution, 600.0 Seconds Maximum.
FS4 – FS7 : 10.0 Seconds Default Setting, 0.1 Seconds Resolution, 6000 Seconds Maximum.
P1-04 Deceleration ramp time See Below 5.0 / 10.0 Seconds
Deceleration ramp time from base speed (P1-09) to standstill in seconds. When set to zero, it will coast
to stop the motor.
FS2 & FS3 : 5.0 Seconds Default Setting, 0.01 Seconds Resolution, 600.0 Seconds Maximum.
FS4 – FS7 : 10.0 Seconds Default Setting, 0.1 Seconds Resolution, 6000.0 Seconds Maximum.
P1-05 Stop mode 0 4 0 -
0 Ramp
When the enable signal is removed, the drive will ramp to stop, with
the rate controlled by P1-04 as described above. In this mode, the drive
brake transistor (where tted) is disabled.
1 Coast
When the enable signal is removed, the drive output is immediately
disabled, and the motor will coast (freewheel) to stop. If the load can
continue to rotate due to inertia, and the drive may possibly be re-
enabled whilst the motor is still rotating, the spin start function (P2-26)
should be enabled. In this mode, the drive brake transistor (where tted)
is disabled.
2
Ramp, brake chopper
enabled
When the enable signal is removed, the drive will ramp to stop, with the
rate controlled by P1-04 as described above. The PACMotion VFD Brake
chopper is also enabled in this mode.
3
Coast, brake chopper
enabled
When the enable signal is removed, the drive output is immediately
disabled, and the motor will coast (freewheel) to stop. If the load can
continue to rotate due to inertia, and the drive may possibly be re-
enabled whilst the motor is still rotating, the spin start function (P2-26)
should be enabled. The drive brake chopper is enabled in this mode;
however, it will only activate when required during a change in the drive
frequency setpoint, and will not activate when stopping.
4 AC Flux Braking
As Option 0, but additionally, AC Flux braking is used to increase the
available braking torque.
P1-06 Energy optimiser 0 1 0 -
0 Disabled
1 Enabled
When enabled, the Energy Optimiser attempts to reduce the overall
energy consumed by the drive and motor when operating at constant
speeds and light loads. The output voltage applied to the motor is
reduced. The Energy Optimiser is intended for applications where the
drive may operate for some periods of time with constant speed and
light motor load, whether constant or variable torque.
P1-07 Motor rated voltage / back EMF Drive Rating Dependent Volts
This parameter should be set to the rated (nameplate) voltage of the motor.
P1-08 Motor rated current Drive Rating Dependent Amps
This parameter should be set to the rated (nameplate) current of the motor.
P1-09 Motor rated frequency 10 500 50 (60) Hz
This parameter should be set to the rated (nameplate) frequency of the motor.
