6. Parameters

6.1. Standard Parameters

Par. Description
P-01 Maximum Frequency / Speed Limit
Maximum output frequency or motor speed limit – Hz or RPM. If P-10 >0, the value entered / displayed is in RPM
P-02 Minimum Frequency / Speed Limit
Minimum speed limit – Hz or RPM. If P-10 >0, the value entered / displayed is in RPM
P-03 Acceleration Ramp Time
Acceleration ramp time from zero Hz / RPM to base frequency (P-09) in seconds.
P-04 Deceleration Ramp Time
Deceleration ramp time from base frequency (P-09) to standstill in seconds. When set to 0.00, the value of P-24 is used.
P-05 Stopping Mode
0 : Ramp To Stop with Mains Loss Ride Through. When the enable signal is removed, the drive will ramp to stop, with the rate
controlled by P-04. If the mains supply is lost, the drive will try to continue running by reducing the speed of the load, and using the
load as a generator.
1 : Coast to Stop. When the enable signal is removed, or if the mains supply is lost, the motor will coast (freewheel) to stop
2 : Ramp To Stop. When the enable signal is removed, the drive will ramp to stop, with the rate controlled by P-04. If the mains
supply is lost the drive will ramp to stop using the P-24 decel ramp.
3 : AC Flux Braking. As setting 2, but AC flux braking is also applied, increasing the level of available braking torque.
P-06 Energy Optimiser
0 : Disabled
1 : Enabled. When enabled, the Energy Optimiser attempts to reduce the overall energy consumed by the drive and motor by
reducing the output voltage during constant speed, light load operation. 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.
P-07 Motor Rated Voltage / Back EMF at rated speed (PM /
BLDC)
For Induction Motors, this parameter should be set to the rated (nameplate) voltage of the motor (Volts).
For Permanent Magnet or Brushless DC Motors, it should be set to the Back EMF at rated speed.
P-08 Motor Rated Current
This parameter should be set to the rated (nameplate) current of the motor
P-09 Motor Rated Frequency
This parameter should be set to the rated (nameplate) frequency of the motor
P-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 VSD 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 If P-09 value is changed, P-10 value is reset to 0
P-11 Low Frequency Torque Boost Current
Low frequency torque can be improved by increasing this parameter. Excessive boost levels may however result in high motor
current and increased risk of tripping on Over Current or Motor Overload (refer to section 10.1)
This parameter operates in conjunction with P-51 (Motor Control Mode) as follows :-
P-51 P-11
0 0
>0
1 All
2, 3, 4 All
For IM motors, when P-51 = 0 or 1, a suitable setting can usually be found by operating the motor under very low or no load
conditions at approximately 5Hz, and adjusting P-11 until the motor current is approximately the magnetising current (if known) or
in the range shown below.
Frame Size 1 : 60 – 80% of motor rated current
Frame Size 2 : 50 – 60% of motor rated current
Frame Size 3 : 40 – 50% of motor rated current
Frame Size 4 : 35 – 45% of motor rated current.
Boost is automatically calculated according to autotune data
Voltage boost = P-11 x P-07.This voltage is applied at 0.0Hz, and linearly reduced until P-09 / 2
Voltage boost = P-11 x P-07.This voltage is applied at 0.0Hz, and linearly reduced until P-09 / 2
Boost current level = 4*P-11*P-08
