6.0 Parameters
6.1 Parameter Set Overview
The Fenner QD:Neo set consists of 6 groups as follows:
• Group 0 - Read only monitoring parameters
• Group 1 - Basic configuration parameters
• Group 2 - Extended parameters
• Group 3 - PID control parameters
• Group 4 - High performance motor control parameters
• Group 5 - Field bus parameters
When the Fenner QD:Neo 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 the parameter groups 1-5 can be accessed, along with the first 38 parameters in Group 0.
6.2 Parameter Group 1 - Basic Parameters
Par Parameter Name
Minimum Maximum Default Units
P1-01
Maximum Frequency / Speed Limit
P1-02 500.00 50.0 (60.0) Hz/rpm
Maximum output frequency or motor speed limit - Hz or rpm.
If P1-10>0, the value entered/displayed is in rpm
P1-02
Minimum Frequency / Speed Limit
0.0 P1-01 0.0 Hz/rpm
Minimum speed limit - Hz or rpm
If P1-10>0, the value entered/displayed is in rpm
P1-03
Acceleration Ramp Time
See below 5.0 Seconds
Acceleration ramp time from 0 to base speed (P-1-09) in seconds
P1-04
Deceleration Ramp Time
See Below 5.0 Seconds
Deceleration ramp time from base speed (P1-09) to standstill in seconds. When set to zero, fastest possible ramp time
without trip is activated.
P1-05
Stop Mode
0 3 0 -
0 : Ramp to Stop. When the enable signal is removed, the drive will ramp to stop, with the rate controlled by P1-04 as
described above. In this mode, the drive brake transistor (where fitted) is disabled.
1 : Coast to stop. When the enable signal is removed, the drive output is immediately disabled, and the motor will coast (free
wheel) to stop. If the load can continue to rotate due to inertia, and the drive may possibly be re-enabled whilst the motor is still
rotating, the spin start function (P2-26) should be enabled. In this mode, the drive brake transistor (where fitted) is disabled.
2 : Ramp to Stop. When the enable signal is removed, the drive will ramp to stop, with the rate controlled by P1-04 as
described above. The Fenner QD brake chopper is also enabled in this mode.
3 : Coast to Stop. When the enable signal is removed, the drive output is immediately disabled, and the motor will coast
(freewheel) to stop. If the load can continue to rotate due to inertia, and the drive may possibly be re-enabled whilst the mo-
tor is still rotating, the spin start function (P2-26) should be enabled. The drive brake chopper is enabled in this mode, how-
ever it will only activate when required during a change in the drive frequency setpoint, and will not activate when stopping.
P1-06
Energy Optimser
0 1 0 -
Only active when enhanced V/F motor control mode is selected (P4-01=2)
0 : Disabled.
1 : Enabled. When enabled the Energy Optimiser attempts to reduce the overall energy consumed by the drive and mo-
tor when operating at constant speeds and light loads. The output voltage applied to the motor is reduced. 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.
P1-07
Motor Rated Voltage
Drive Rating Dependent Volts
This parameter should be set to the rated (nameplate) voltage of the motor (Volts)
P1-08
Motor Rated Current
Drive Rating Dependent Volts
This parameter should be set to the rated (nameplate) current of the motor
P1-09 Motor Rated Frequency
25 500 50 (60) Hz
This parameter should be set to the rated (nameplate) frequency of the motor
P1-10
Motor Rated Speed
0 30000 0 rpm
This parameter can be optionally 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 Fenner QD Neo 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.
