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
.
bPIDEnableInfluenceRamp
BOOL
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
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
Adaptation of gain Vp set in C00222 in percent
• Scaling: 16384 ≡ 100 %
• Internal limitation to ± 199.99 %
• Changes can be done online.
nPIDSetValue_a
INT
Sensor and process setpoint for operating modes 2, 4 and 5
• Scaling: 16384 ≡ 100 %
• Internal limitation to ± 199.99 %
nPIDActValue_a
INT
Speed or actual sensor value (actual process value)
• Offset and gain for this input signal can be set in C00698
and C00672.
• Scaling: 16384 ≡ 100 %
• Internal limitation to ± 199.99 %
nPIDInfluence_a
INT
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 %
MCK basic functions
bMBrakeRelease
BOOL
Holding brake control: Release/apply brake
• In conjunction with the operating mode selected in C02580
(Lenze setting: "Brake control off").
FALSE Apply brake.
• During automatic operation, the internal brake logic controls the
brake.
TRUE Release brake manually (forced release).
• Note!
The brake can also be released when 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.
