1.3. Parameter Descriptions

1.3.1. Parameter Group 1 – Basic Parameters
Par. Name
P1-01 Maximum Frequency / Speed Limit
Maximum output frequency or motor speed limit – Hz or rpm.
If P1-10 > 0, the value entered / displayed is in Rpm
The value which may be entered by the user is limited by the lower of the following :-
5 x P1-09 value
P2-24 / 16
P1-02 Minimum Frequency / Speed Limit
Minimum speed limit – Hz or rpm.
If P1-10 >0, the value entered / displayed is in Rpm
P1-03 Acceleration Ramp Time
Acceleration ramp time from 0 to base speed (P-1-09) in seconds.
Note
For Optidrive P2 units Frame Sizes 2 and 3, the parameter range is adjustable between 0.00 and 600.0 seconds
For Optidrive P2 units Frame Sizes 4 and above, the parameter range is adjustable between 0.0 and 6000.0 seconds
P1-04 Deceleration Ramp Time
Deceleration ramp time from base speed (P1-09) to standstill in seconds. When set to zero, fastest possible ramp time without trip is
activated
Note
For Optidrive P2 units Frame Sizes 2 and 3, the parameter range is adjustable between 0.00 and 600.0 seconds
For Optidrive P2 units Frame Sizes 4 and above, the parameter range is adjustable between 0.0 and 6000.0 seconds
P1-05 Stop Mode
This parameter has several functions :-
- To enable / disable the brake chopper during deceleration
- To select the stopping mode (Ramp or Coast)
- To enable the AC Flux Braking function
0 : Ramp To Stop. 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 is disabled.
1 : Coast to Stop. 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 is disabled.
2 : Ramp To Stop, 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 brake chopper is also enabled in this mode.
3 : Coast to Stop, 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. AC Flux braking provides improved braking torque during stopping and dceceleration. In this mode, the brake
chopper is disabled, however braking torque is improved.
P1-06 Energy Optimiser
Only active when enhanced V/F motor control mode is selected (P4-01 = 2).
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
This parameter should be set to the rated (nameplate) voltage of the motor (Volts)
The factory default setting of this parameter is drive model dependent as follows :-
All kw & HP models intended for 200 – 240 volt operation (e.g. ODP-2-x2xxx-xxF4x) : Factory setting = 230 Volts, Maximum 250 Volts
All kW models intended for 380 – 480 volt operation (e.g. ODP-2-x4xxx-3KFxN) : Factory setting = 400 Volts, Maximum 500 Volts
All HP models intended for 380 – 480 volt operation (e.g. ODP-2-x4xxx-3HFxN) : Factory setting = 460 Volts, Maximum 500 Volts
When this parameter is set to the motor nameplate voltage, the output voltage from the drive is controlled automatically and
maintained at the correct level wherever possible regardless of variations in supply voltage or DC Bus Voltage.
When P1-07 = 0, the voltage compensation function of the inverter is disabled. The output voltage applied to the motor will increase
or decrease with changes in the DC Bus voltage.
Note
The RMS output voltage from the inverter can never exceed the incoming supply voltage.
P1-08 Motor Rated Current
This parameter should be set to the rated (nameplate) current of the motor.
The factory default setting of this parameter is the set to the maximum continuously available output current of the drive
