Process controller

• In the Lenze setting, the process controller is deactivated.

• The activation is executed by selecting the operating mode in

C00242

.

• For a detailed functional description see FB

L_PCTRL_1

.

bPIDEnableInfluenceRamp

BOOL

C00701/15

Activate ramp for influencing factor

FALSE Influencing factor of the PID controller is ramped down to "0".

TRUE Influencing factor of the PID controller is ramped up to the value

nPIDInfluence_a.

bPIDIOff

BOOL

C00701/16

Switch off the I-component of the process controller

• In conjunction with the operating mode set in

C00242

(Lenze setting: "Off").

TRUE I-component of the process controller is switched off.

nPIDVpAdapt_a

INT

C00700/6

Adaptation of gain Vp set in

C00222

in percent

• Scaling: 16384 ≡ 100 %

• Internal limitation to ± 199.99 %

• Changes can be done online.

nPIDActValue_a

INT

C00700/7

Speed or actual sensor value (actual process value)

• Scaling: 16384 ≡ 100 %

• Internal limitation to ± 199.99 %

nPIDInfluence_a

INT

C00700/8

Limitation of the influencing factor in percent

• The influence factor of the PID controller can be limited to a certain value (-

199.99% ... + 199.99%) via nPIDInfluence_a.

• Scaling: 16384 ≡ 100 %

• Internal limitation to ± 199.99 %

nPIDSetValue_a

INT

C00700/9

Sensor setpoint or process setpoint for operating mode 2

• Scaling: 16384 ≡ 100 %

• Internal limitation to ± 199.99 %

bPIDInAct

BOOL

C00701/34

(from version 04.00.00)

Deactivate process controller temporarily (stop)

• Changes can be done online.

TRUE

• The current output value is frozen.

• The internal control algorithm is stopped.

• However, a setpoint selected via input nNSet_a is still provided in

operating modes 0/1/4/5.

bPIDOff

BOOL

C00701/35

(from version 04.00.00)

Reset the entire PID controller

TRUE

• The I component of the controller is set to zero.

• The controller output is set to zero.

• The internal control algorithm is stopped.

Holding brake control

• In the Lenze setting, the holding brake control is deactivated.

• The activation is executed by selecting the operating mode in

C02580

.

• For a detailed function description see chapter entitled "

Holding brake control

".

bBrkRelease

BOOL

C00701/19

Manual release of the brake in connection with the selected operating mode.

• In the Lenze setting, this input is connected to the digital input DI5.

FALSE Do not release the brake manually.

TRUE Release brake manually (forced release).

Note!

The brake can also be released if the controller is inhibited!

• During automatic operation, the internal brake logic is

deactivated and the brake is released (supervisor operation). If a

controller inhibit has been set by the brake control, it will be

deactivated.

• In semi-automatic operation, the brake is released including

feedforward control.
