dnMotorPosAct_p
DINT
Current position in [increments]
• If the gearbox factor position encoder (
) is equal to "1", the motor
position is output.
• Otherwise, if the gearbox factor position encoder (
) is not equal to "1"
and a position encoder has been set in
, a position referring to the position
encoder is output.
dnMotorDeltaPosAct_p
DINT
Current following error in [increments]
• Following error = Difference between set position and actual position
• If the gearbox factor position encoder (
) is equal to "1", the motor
following error is output.
• Otherwise, if the gearbox factor position encoder (
) is not equal to "1"
and a position encoder has been set in
, a following error referring to the
position encoder is output.
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

nOutputSpeedCtrl_a
INT
Speed controller output
• Scaling: 16384 ≡ 100 % M
max
• 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
•
< 650 Hz: 16384 ≡ 327.68 Hz (24000 ≡ 480.00 Hz)

> 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 (
• Servo control (SC) or vector control (SLVC):
16384 ≡ 100 % M
