Outputs
Process controller
• In the Lenze setting, the process controller is deactivated.
• The activation is executed by selecting the operating mode in C242 .
• For a detailed functional description see FB L_PCTRL .
bPIDEnableInfluenceRamp
BOOL
C701/15
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.
bPIDOff
BOOL
C701/16
Switch off I-component of the process controller
• In conjunction with the operating mode set in C242
(Lenze setting: "Off).
TRUE I-component of the process controller is switched off.
nPIDVpAdapt_a
INT
C700/6
Adaptation of the gain Vp set in C222 in percent
• Scaling: 16384 ≡ 100 %
• Internal limitation to ±199.9 %
• Changes can be done online.
nPIDActValue_a
INT
C700/7
Speed or actual sensor value (actual process value)
• Scaling: 16384 ≡ 100 %
• Internal limitation to ±199.9 %
nPIDInfluence_a
INT
C700/8
Limitation of the influencing factor in percent
• The influence factor of the PID controller can be limited to a certain value (-
199.9% ... +199.9%) via nPIDInfluence_a.
• Scaling: 16384 ≡ 100 %
• Internal limitation to ±199.9 %
nPIDSetValue_a
INT
C700/9
Sensor setpoint or process setpoint for operating mode 2
• Scaling: 16384 ≡ 100 %
• Internal limitation to ±199.9 %

Value/meaning
Device control
wDeviceStateWord
WORD
Status word of the controller (based on DSP-402)
• The status word contains information on the currents status of the drive control-
ler.
• In control mode "30: CAN", the status word is transmitted to the master control
as process data word via the LP_CanOut1 port block.
• For a detailed description of the individual status bits, see subchapter entitled
" Process data assignment for control via CAN .
• Display parameter: C150
wDeviceAuxStateWord
WORD
Extended status word of the controller
wDetermFailNoLow
WORD
Display of the current error (Low-Word)
wDetermFailNoHigh
WORD
Display of the current error (High-Word)
bDriveFail
BOOL
TRUE Controller in error status
• " Fault " device state is active.
bDriveReady
BOOL
TRUE Controller is ready for operation.
• " SwitchedON " device state is active.
• The drive is in this device state if the DC bus voltage is applied and
the controller is still inhibited by the user (controller inhibit).
