Installation & Operating Instructions
A
DJUSTING THE VOLTAGE / FREQUENCY (V/F) CHARACTERISTICS
The V/f characteristic is defined by several parameters as shown. Reducing the
voltage at a particular frequency reduces the current in the motor and hence the
torque and power. The V/f curve can be further modified by using P-28 and P-29,
where P-28 determines the percentage increase or decrease of the voltage applied
to the motor at the frequency specified in P-29. This can be useful if motor
instability is experienced at certain frequencies, if this is the case increase or
decrease the voltage (P-28) at the speed of instability (P-29).
For applications requiring energy saving, typically HVAC and pumping, the energy
optimiser (P-06) parameter can be enabled. This automatically reduces the applied
motor voltage on light load.
P-00 READ ONLY DRIVE STATUS PARAMETERS
7.2.1. PARAMETER GROUP ZERO ACCESS AND NAVIGATION
When P-14 = P-37, all P-00 parameters are visible. Default value is 101.
When the user scrolls to P-00, pressing will display “P00-HH”, where HH represents the secondary number within P-00.
(i.e. 1 to 20). The User can then scroll to the required P-00 parameter.
Pressing once more will then display the value of that particular group zero parameter.
For those parameters which have multiple values (e.g. software ID), pressing the and keys will display the different
values within that parameter.
Pressing returns to the next level up. If is then pressed again (without pressing or ), the display changes to the
next level up (main parameter level, i.e. P-00).
If or is pressed whilst on the lower level (e.g. P00-05) to change the P-00 index, pressing <NAVIGATE> quickly displays
that parameter value.
8. ANALOG AND DIGITAL INPUT CONFIGURATIONS
8.1. TERMINAL MODE (P-12 =0)
Negative Preset Speeds will be inverted if Run Reverse selected.

P00-12 Run time since last trip (2) 0 to 99 999 hours
enable only if a trip occurred (under-volts not considered a trip) –
not reset by power down / power up cycling unless a trip occurred
prior to power down

lower than the selected frequency in P-17 if the drive is too hot.
Frequency
The drive will automatically reduce the switching frequency to
prevent an over temperature trip and maintain operation.
