7. Parameters
7.1. Parameter Set Overview
The HP Combi Flow Extended Parameter set consists of 7 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 – Application Specific Functions Parameter Set
Group 0 – Monitoring and Diagnostic Parameters (Read Only).
When the HP Combi Flow 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 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 = 201), which allows access to all
parameter groups and ranges.

Maximum Frequency/Speed Limit
Motor Rating Dependent
Hz / Rpm
Maximum output frequency or motor speed limit – Hz or Rpm.
If P1-10 >0, the value entered / displayed is in Rpm.
NOTE
The maximum possible setting is limited to the lowest value of:
5 x P1-09
5 x P1-10

P1-02
Minimum Frequency/Speed Limit
Motor Rating Dependent
Hz / Rpm
Minimum speed limit – Hz or Rpm.
If P1-10 >0, the value entered / displayed is in Rpm.

Acceleration ramp time from 0 to base speed (P1-09) in seconds.
P1-04
Deceleration Ramp Time

Ramp
When the enable signal is removed, the drive will ramp to stop, with the rate controlled by
P1-04 as described above.
1
Coast
When the enable signal is removed the motor will coast (freewheel) to stop.
2
AC Flux Braking
Provides additional braking torque capability when decelerating.
P1-07
Motor Rated Voltage / kE
0
Motor Rating Dependent
Volts
For PM Motors
- Enter the back EMF at rated motor speed.
P1-08
Motor Rated Current
Motor Rating Dependent
Amps
This parameter should be set to the rated (nameplate) current of the motor.
P1-09
Motor Rated Frequency
Motor Rating Dependent
Hz
This parameter should be set to the rated (nameplate) current of the motor.
P1-10
Motor Rated Speed
Motor Rating Dependent
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 HP Combi Flow 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.
