Outputs
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 )
bDcBrakeOn
C00833/34 | BOOL
Activate DC injection brake
FALSE Deactivate DC-injection braking
TRUE Activate DC-injection braking
bTorqueLimitAdaptOn
C00833/98 | BOOL
Adaptation of torque limitation
TRUE Activate adaptation of torque limitation.
nTorqueLimitAdapt_a
C00830/70 | INT
Value for adaptation of torque limitation
• Scaling: 16384 ≡ 100 % nTorqueMotLimit_a and nTorqueGenLimit_a
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 ( 289)
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.
