7. Parameters

7.1. Parameter Set Overview
The Optidrive HVAC Parameter set consists of 9 groups as follows:

Group 1 – Basic Parameter Set

Group 2 – Extended Parameter Set

Group 3 – User PID Control Parameter Set

Group 4 – Motor Control Parameters

Group 5 – Field Bus Communications Parameter Set

Group 8 – HVAC Specific Functions Parameter Set

Group 0 –Monitoring and Diagnostic Parameters (Read Only)
When the Optidrive is reset to factory defaults, or is in its factory supplied state, only Group 1 Parameters can be accessed. In order to allow
access to parameters from the higher level groups, P1-14 must be set to the same value as P2-40 (Default setting = 10*. With this setting,
parameter groups 1 – 5 and group 8 can be accessed, along with the first 39 parameters in Group 0. These parameters are listed in the tables
below.
For advanced parameter access, P1-14 can be set to the same value as P6-30 (Default setting = 20*, which allows access to all parameter
groups and ranges. Advanced parameter descriptions are listed in the advanced user guide.
Values given in brackets () are default settings for horsepower rated drive models.
7.2. Parameter Group 1 – Basic Parameters
Par Parameter Name
P1-01 Maximum Speed Limit
Maximum output frequency or motor speed limit – Hz or rpm.
If P1-10 >0, the value entered / displayed is in Rpm
P1-02 Minimum 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.
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
P1-05 Stop Mode Select
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 motor will coast (freewheel) to stop
P1-06 Energy Optimiser
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.
P1-07 Motor Rated Voltage
This parameter should be set to the rated (nameplate) voltage of the motor (Volts)
P1-08 Motor Rated Current
This parameter should be set to the rated (nameplate) current of the motor
Parameter Range: Frame size 2,
P1-09 Motor Rated Frequency
This parameter should be set to the rated (nameplate) frequency of the motor
P1-10 Motor Rated Speed
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.
P1-11 Voltage Boost
Voltage boost is used to increase the applied motor voltage at low output frequencies, in order to improve low speed and starting
torque. Excessive voltage boost levels may result in increased motor current and temperature, and force ventilation of the motor
may be required.
An automatic setting () is also possible, whereby the Optidrive will automatically adjust this parameter based on the motor
parameters measured during an auto-tune (See Parameter P4-02).
