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.
