Detailed Description of the Parameters .
72 | CTW900
P0406 – Tacho Voltage at 1000 rpm
Adjustable Range: 0.0 to 300.0 V Factory Setting: 60.0 V
Properties: CFG1
Groups of 01 PARAMETER GROUPS
Access via HMI:

24 Speed Feedback ........
Description:
It defines the voltage generated by the DC tacho when it is spinning at 1000 rpm.
It must be set with the value informed on the nameplate of the DC tacho.
P0407 – Gain Setting of the DC Tacho
Adjustable Range: 0.000 to 1.999 Factory Setting: 1.000
Properties:
Groups of
01 PARAMETER GROUPS
Access via HMI:

24 Speed Feedback ........
Description:
It allows a fine tuning of the speed measured by the DC tacho so as to correct the value calculated when
compared to the measurement of the external tachometer.
Refer to section 6.3.2 for further details about the most suitable way to make this adjustment.
7.3.6 Control Options [25]
Using this group it is possible to disable the field control and also configure the regulation mode of the armature
circuit.
P0297 – Field Control
Adjustable Range: 0 = Enabled Factory Setting: 0
1 = Disabled
Properties: CFG2
Groups of 01 PARAMETER GROUPS
Access via HMI:  25 Control Options ........
Description:
It defines if the field control is enabled or disabled.
By configuring P0297 = 1 (Disable), the field firing pulses are disabled, and the converter will not monitor the
field current.
ATTENTION!
With P0297 = 1 the protection of field loss (F074) will be inactive.
P0299 – Control Mode
Adjustable Range: 0 = Speed + Torque Factory Setting: 0
1 = Torque
Properties: CFG1
Groups of 01 PARAMETER GROUPS
Access via HMI:

25 Control Options ........
Description:
In some applications in which you want to control only the motor torque, the CTW900 can be configured to
regulate only the armature current, ignoring the speed feedback value. In order to do so, you must set P0299 =
1 (Torque Mode).
