Par. Parameter Name Minimum Maximum Default Units
P1-11 Torque Boost Motor Rating Dependent %
Torque Boost is used to increase the applied motor voltage and hence current at low output frequencies. This can improve low
speed and starting torque. Increasing the boost level will increase motor current at low speed, which may result in the motor
temperature rising - force ventilation of the motor may then be required. In general, the lower the motor power, the higher the boost
setting that may be safely used.
P1-12 Primary Command Source 0 6 0 -
0 Terminal Control
The drive responds directly to signals applied to the control terminals.
1 Keypad control -
uni-directional
The drive can be controlled in the forward direction only using an internal or remote
Keypad.
2 Keypad control -
uni-directional
As above.
3 PID Control
The output frequency is controlled by the internal PID controller.
4 Fieldbus Control
By the selected Fieldbus (Group 5 Parameters) – Excludes BACnet (see option 6).
5 Slave Mode
The drive acts as a Slave to a connected HP Combi Flow operating in Master Mode.
6 BACNet MS/TP Mode
Drive communicates / responds as a slave within a BACnet network.
P1-13 Digital Input Function 0 14 1 -
Defines the function of the digital inputs. When set to 0 the inputs are user defined using group 9 parameters or the PLC software
function in the software package. When set to a value other than 0 the digital input configuration is defined by digital input definition
table (see section 8.1. Digital Input Configuration Parameter P1-13).
P1-14 Extended Menu Access 0 30000 0 -
Parameter Access Control. The following settings are applicable:
P1-14 <> P2-40 and P1-14 <> P6-30: Allows access to Parameter Group 1 only.
P1-14 = P2-40 (101 default): Allows access to Parameter Groups 0 - 5 and group 8.
P1-14 = P6-30 (201 default): Allows access to Parameter Groups 0 - 9.
