bDeltaPosOn
C00833/35 | BOOL
Activate position difference as setpoint selection
• In order to position the motor shaft, the position control function can work
within the motor control function with the absolute position setpoint
dnPosSetValue_p or alternatively with the speed setpoint nSpeedSetValue_a and
the position difference dnDeltaPos_p.
FALSE Positioning with position setpoint dnPosSetValue_p.
TRUE Positioning with speed setpoint nSpeedSetValue_a and position
difference dnDeltaPos_p.
dnDeltaPos_p
C00834/4 | DINT
Position difference (following error input)
• Difference between setpoint position and actual position in [increments]
• Is used for position control if bDeltaPosOn = TRUE.
• Scaling: 65535 ≡ 1 revolution
dnPosSetValue_p
C00834/5 | DINT
Absolute position setpoint in [increments]
• Is used for position control if bDeltaPosOn = FALSE.
• Scaling: 65535 ≡ 1 revolution
bPosDerivativeOn
C00833/67 |BOOL
Create a setpoint for the speed controller from the position setpoint
• For highly dynamic control systems, the setpoint for the speed controller can be
created from the absolute position setpoint dnPosSetValue_p instead of the
speed setpoint nSpeedSetValue_a  Position control/additive speed specification
TRUE Create a speed setpoint from the position setpoint.
• The absolute position setpoint dnPosSetValue_p is differentiated
and a speed value is created which is the setpoint for the speed
controller.
• Internal limitation of 65536 increments/ms.
bMotorRefOffsetOn
C00833/68 | BOOL
Set home position ("referencing on the fly")
TRUE Set home position to value dnMotorRefOffset_p.
dnMotorRefOffset_p
C00834/6 | DINT
Home position in [increments]
• Scaling: 65535 ≡ 1 revolution
bQspOn
C00833/33 | BOOL
Quick stop
FALSE Deactivate quick stop
TRUE Activate quick stop
nPWMAngleOffset_a
C00830/32 | INT
Angle step change of output voltage phasor
• Scaling: 65535 ≡ 1 revolution
bSpeedCtrlIOn
C00833/31 | BOOL
Directly set the I-component of speed controller
• In order to statically specify a minimum torque, e.g. when a load is being lifted.
TRUE Se the I-component of the speed controller to the value
nSpeedCtrlI_a.
nSpeedCtrlI_a
C00830/24 | INT
Value of the speed controller integrator
• Scaling depends on the selected motor control:
• V/f control (VFCplus + encoder):
16384 ≡ 100 % reference speed ( C00011 )
• Servo control (SC) or vector control (SLVC):
16384 ≡ 100 % M
max
( C00057 )
nSpeedSetValue_a
C00830/22 | INT
Speed setpoint
• Scaling: 16384 ≡ 100 % reference speed ( C00011 )
bTorquemodeOn
C00833/30 | BOOL
Selection: Speed/Torque control
FALSE Speed control with torque limitation
TRUE Torque control with speed limitation
nTorqueSetValue_a
C00830/27 | INT
Torque setpoint / additive torque
• Scaling: 16384 ≡ 100 % M
max
( C00057 )
