P1-01
Maximum Frequency / Speed Limit
P1-02
500.0 / 30000
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
The value which may be entered by the user is limited by the lower of the following :-
5 x P1-09 value OR P2-24 / 16
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
0.0
6000
30
Seconds
Acceleration ramp time from 0 to base speed (P-1-09) in seconds.
P1-04
Deceleration Ramp Time
0.0
6000
30
Seconds
Deceleration ramp time from base speed (P1-09) to standstill in seconds. When set to zero, fastest possible ramp time without trip is
activated
P1-05
Stop Mode
0

0
-
This parameter has several functions :-
- 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.
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.
2 : AC Flux Braking. AC Flux braking provides improved braking torque during stopping and dceceleration.
P1-07
Motor Rated Voltage
0
See Below
See Below
Volts
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. ODV-3-x2xxx-xxF1x-xN) : Factory setting = 230 Volts, Maximum 250
Volts
All kW & HP models intended for 380 – 480 volt operation (e.g. ODV-3-x4xxx-3F1x-xN) : Factory setting = 400 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
-
-
See Below
Amps
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
P1-09
Motor Rated Frequency
10
500
50 (60)
Hz
This parameter should be set to the rated (nameplate) frequency of the motor.
The factory default setting of this parameter is drive model dependent as follows :-
All kW models : Factory setting = 50Hz
All HP models : Factory setting = 60 Hz
P1-10
Motor Rated Speed
0
30000
0
Rpm
This parameter can optionally be set to the rated (nameplate) rpm of the motor. When set to the default value of zero, all speed
related parameters are displayed in Hz, and the slip compensation for the motor is disabled. Entering the value from the motor
nameplate enables the slip compensation function, and the Optidrive display will now show motor speed in estimated rpm. All speed
related parameters, such as Minimum and Maximum Speed, Preset Speeds etc. will also be displayed in Rpm.
