CTW900 | 73
In this condition, the Speed Reference (P0001) becomes the Torque Reference, and its unit displayed in the
monitoring mode of the HMI changes to “%”, and this percentage is expressed in relation to the converter rated
current (P0295).
Besides that, the value displayed on the upper right corner of the HMI becomes the armature current (P0003),
replacing the present speed value.
Note:
The ramps remain active in the Torque Mode.
ATTENTION!
With P0299 = 1 the overspeed protection (F150) will be inactive.
7.3.7
Regulators [26]
This group contains parameters related to the regulators of the CTW900, which define the dynamic behavior of
all control loops of the converter.
All the regulators are implemented in the parallel configuration, where the gains are independent from each
other.

Description:
Main gains of the speed regulator, which must be set so as to optimize the dynamic response of the speed
loop.
In a general way, we can say the Proportional gain (P0159) stabilizes sudden speed changes, whereas the
Integral gain (P0160) corrects the error between the reference and effective speed, as well as improves the
response in torque at low speeds.
In order to set these gains properly, follow the procedures described in sections 6.4.1 and 6.4.3.
Note:
In case there are some digital input set for the “Speed Reg. Gains” function, the CTW900 will use the
second gain set (P0161 and P0162) when this Dix is active (24V).
P0161 – Proportional Gain 2 of the Speed Regulator
Adjustable Range:
0.0 to 63.9
Factory Setting:
8.0
P0162 – Integral Gain 2 of the Speed Regulator
Adjustable Range:
0.00 to 9.99
