6. Parameters
6.1. Parameter Set Overview
The Parameter set consists of 6 groups as follows:
•
Group 0 – Read Only Monitoring Parameters
• Group 1 – Basic Configuration Parameters
•
Group 2 – Extended Parameters
•
Group 3 – PID Control Parameters
• Group 4 – High Performance Motor Control Parameters
•
Group 5 –Field Bus Parameters
When the Drive 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 = 101). With this setting, parameter
groups 1 – 5 can be accessed, along with the first 38 parameters in Group 0.
6.2. Parameter Group 1 – Basic Parameters
Par Parameter Name 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 (P‐1‐09) in seconds.
Note
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, fastest possible ramp time without trip is
activated
Note
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 3 0 ‐
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 (where fitted) 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 (where fitted) is disabled.
2 : 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. The Drive Brake chopper is also enabled in this mode.
3 : 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. 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.
P1‐06 Energy Optimiser 0 1 0 ‐
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 Drive Rating Dependent Volts
This parameter should be set to the rated (nameplate) voltage of the motor (Volts)
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
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 Drive 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.
Note : When the drive is operated with the optional Encoder Feedback Interface, this parameter must be set to the correct
nameplate Rpm of the connected motor.
