Use this parameter to set the P-gain of the torque limit controller.
This parameter determines the P-gain of the torque limit controller. It is used in Open Loop control mode only.
10.288 (ID 611) Torque Limit Control I-Gain
Location in the menu: P2.10.3 (Multi-purpose Control Application)
Use this parameter to set the I-gain of the torque limit controller.
This parameter determines the I-gain of the torque limit controller. It is used in Open Loop control mode only.
10.289 (ID 612) Magnetizing Current
Location in the menu:
P2.6.14.1 (Standard Application, Local/Remote Control Application, Multi-step Speed Control Application, PID Control Applica-
tion)
P2.6.17.1
(Multi-purpose Control Application, VACON
®
NXS)
P2.6.15.1
(Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to set the magnetizing current of the motor.
The magnetizing current (no-load current) of the motor identifies the values of the U/f parameters when they are given before the
identification run. If the value is set to 0, the magnetizing current is calculated internally.
In VACON
®
NXP, the values of the U/f parameters are identified according to the magnetizing current if given before identification.
See 10.625 Closed Loop Parameters (IDs 612–621) .
10.290 (ID 613) Speed Control P-Gain
Location in the menu:
P2.6.14.2
(Standard Application, Local/Remote Control Application, Multi-step Speed Control Application, PID Control Applica-
tion)
P2.6.17.2 (Multi-purpose Control Application, VACON
®
NXS)
P2.6.15.2 (Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to set gain for the speed controller as a percentage per Hz.
When the gain value is 100%, the nominal torque reference is produced at the speed controller output for a frequency error of 1 Hz.
See
10.625 Closed Loop Parameters (IDs 612–621) .
10.291 (ID 614) Speed Control I-Time
Location in the menu:
P2.6.14.3 (Standard Application, Local/Remote Control Application, Multi-step Speed Control Application, PID Control Applica-
tion)
P2.6.17.3
(Multi-purpose Control Application, VACON
®
NXS)
P2.6.15.3
(Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to set the integral time constant for the speed controller.
See
10.625 Closed Loop Parameters (IDs 612–621) .
SpeedControl Output(k) = SPC OUT(k-1) + SPC Kp*[Speed Error(k) – Speed Error (k-1)] + Ki*Speed error(k)
where Ki = SPC Kp*Ts/SPC Ti.
10.292 (ID 615) Zero Speed Time at Start
Location in the menu:
P2.6.14.9 (Standard Application, Local/Remote Control Application, Multi-step Speed Control Application, PID Control Applica-
tion
P2.6.17.9 (Multi-purpose Control Application, VACON
®
NXS)
P2.6.15.9 (Multi-purpose Control Application, VACON
®
NXP)
Use this parameter to set the time during which the AC drive stays at zero speed after the start command.
The speed will be released to follow the set frequency/ speed reference after this time has elapsed from the instant where the com-
mand is given. See
10.625 Closed Loop Parameters (IDs 612–621) .
