GFK-3111A PACMotion VFD AC Variable Speed Drive User Guide 47
Par. Description Minimum Maximum Default Units
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 PACMotion VFD 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.
P1-11 Boost voltage 0.0 Drive Rating Dependent %
Voltage boost is used to increase the applied motor voltage at low output frequencies, in order to
improve low speed and starting torque. Excessive voltage boost levels may result in increased motor
current and temperature, and force ventilation of the motor may be required.
An automatic setting (Auto) is also possible, whereby the PACMotion VFD will automatically adjust this
parameter based on the motor parameters measured during an autotune.
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
external or remote Keypad.
2
Keypad control -
bi-directional
The drive can be controlled in the forward and reverse directions using
an external or remote Keypad. Pressing the keypad START button
toggles between forward and reverse.
3 PID Control The output frequency is controlled by the internal PID controller.
4 Fieldbus Mode
Control via Modbus RTU if no eldbus interface option is present,
otherwise control is from the eldbus option module interface.
5 Slave Mode
The drive acts as a Slave to a connected PACMotion VFD operating in
Master Mode.
6 CANopen Mode Control via CAN bus connected to the RJ45 serial interface connector.
P1-13 Control terminals function macro 0 21 1 -
Denes the function of the digital inputs depending on the control mode setting in P1-12. See section
Control Source Selection for more information.
P1-14 Extended menu access 0 30000 0 -
Parameter Access Control. The following settings are applicable:
P1-14 = P2-40 = 101 : Allows access to Extended Parameter Groups 0 – 5
P1-14 = P6-30 = 201 = Allows access to all parameter groups (Intended for experienced users only, usage
is not described in this User Guide).
