Outputs
nInertiaAdapt_a
C00830/96 | INT
(from version 12.00.00)
Adaptation of the moment of inertia
• This process signal can be used during the process to dynamically control the
percentage of the variable moment of inertia (e.g. a reel) set in C00919/1 which
is to be considered for setpoint feedforward control.
• Scaling: 16384 ≡ 100 % moment of inertia - process ( C00919/1 )
bBrakeChopperOn
C00833/130 | BOOL
(from version 12.00.00)
Switch on the internal brake chopper as "brake chopper slave" ( C02866/3 = "1: Yes")
when the controller is configured
 Control of multiple internal brake choppers in the DC-bus system ( 234)
TRUE Switch on internal brake chopper.
nSpeedSetValueInertia_a
C00830/97 | INT
(from version 12.00.00)
Input for differential setpoint feedforward control (torque feedforward control)
• If the selection "1: nSpeedSetValueInertia_a" is set in C00654/1 , this process
signal can be used to preselect any input value (e.g. setpoint of the position or
process controller) for torque feedforward control.
• Scaling: 16384 ≡ 100 % reference speed ( C00011 )
bVfcEcoDisable
C00833/131 | BOOL
(from version 13.00.00)
Deactivate energy optimisation for VFCplusEco
 Improving the behaviour at high dynamic load changes
FALSE Activate energy optimisation.
TRUE Deactivate energy optimisation.

Value/meaning
bLimPosCtrlOut
BOOL
"Position controller output inside the limitation" status signal
TRUE The position controller output is internally limited
nOutputPosCtrl_a
INT
Position controller output
• Scaling: 16384 ≡ 100 % reference speed ( C00011 )
dnMotorPosAct_p
DINT
Current position of the motor shaft in [increments]
dnMotorDeltaPosAct_p
DINT
Current following error in [increments]
• Following error = Difference between set position and actual position
bLimSpeedCtrlOut
BOOL
"Speed controller or manipulating variable of the slip regulator inside the limitation"
status signal
TRUE The speed controller output is internally limited
bLimSpeedSetVal
BOOL
"Reduction or increase of the setpoint speed active" status signal
TRUE Reduction or increase of the setpoint speed by the I
max
controller is
active
wMaxMotorSpeed
C00011 | BOOL
Reference speed ( C00011 )
nOutputSpeedCtrl_a
INT
Speed controller output
• Scaling: 16384 ≡ 100 % M
max
( C00057 )
• In case of the "VFC (+encoder)" motor control, this output is the output of the slip
regulator. In this case, the scaling depends on the reference frequency (display in
C00059 ):
• C00059 < 650 Hz: 16384 ≡ 327.68 Hz (24000 ≡ 480.00 Hz)
• C00059 > 650 Hz: 16384 ≡ 655.36 Hz (12000 ≡ 480.00 Hz)
nSpeedCtrlIAct_a
INT
Current value of speed controller integrator
• Scaling depends on the selected motor control:
• V/f control (VFCplus + encoder):
16384 ≡ 100 % reference speed ( C00011 )
• Vector control (SLVC):
16384 ≡ 100 % M
max
( C00057 )
nEffSpeedSetValue_a
INT
Effective speed setpoint
• Scaling: 16384 ≡ 100 % reference speed ( C00011 )
