nVoltageAdd_a
C00830/31 | INT
Additive voltage impression
• An additional setpoint for the motor voltage can be specified via this process
input.
• If there are, for instance, different loads at the motor output end, it is possible to
apply a voltage boost at the starting time.
• If the value is negative, the voltage is reduced.
• Scaling: 16384 ≡ 1000 V
Stop!
Values selected too high may cause the motor to heat up due to the resulting
current!
bAutoBoostOn
C00833/32 | BOOL
As of version 04.00.00
AutoBoost function
• Motor voltage boost during the starting torque, controlled by process signals
from the function block interconnection.
FALSE Deactivate function
TRUE Activate function
nBoost_a
C00830/26 | INT
Additional setpoint for the motor voltage at speed = 0
• The entire voltage-frequency characteristic is provided with an offset.
• Scaling: 16384 ≡ 1000 V
Stop!
Values selected too high may cause the motor to heat up due to the resulting
current!
bPosCtrlOn
C00833/27 | BOOL
Position/angle control
FALSE Deactivate position/angle control.
TRUE Activate position/angle control.
bDeltaPosOn
C00833/35 | BOOL
Activate position difference as setpoint selection
• For motor shaft positioning, the position control function within motor control
can work with the absolute position setpoint dnPosSetValue_p or, alternatively,
with the speed setpoint nSpeedSetValue_a and the specified following error
dnDeltaPos_p.
FALSE Positioning with absolute position setpoint dnPosSetValue_p.
TRUE Positioning with speed setpoint nSpeedSetValue_a and position
difference dnDeltaPos_p.
dnDeltaPos_p
C00834/4 | DINT
Following error input
• Difference between setpoint position and actual position in [increments]
•Is used if bDeltaPosOn = TRUE.
• Scaling: 65535 ≡ 1 revolution
dnPosSetValue_p
C00834/5 | DINT
Absolute position setpoint in [increments]
• Is used in the case of bDeltaPosOn = FALSE.
• Scaling: 65535 ≡ 1 revolution
bPosDerivativeOn
C00833/67 | BOOL
Activate feedforward control of speed controller
• For highly dynamic control systems, feedforward control of the speed controller
can be switched on. For this purpose, the absolute position setpoint
dnPosSetValue_p must be differentiated and fed in behind the speed controller.
TRUE Differentiation of the position setpoint and limitation to
65536 increments/ms.
• The differentiated value is transferred to the speed control as an
alternative to the speed setpoint. Hence, a speed setpoint is
internally differentiated from the setpoint position and internally
generated.
bMotorRefOffsetOn
C00833/68 | BOOL
Set home position ("referencing on the fly")
TRUE Set home position to value dnMotorRefOffset_p.
