Motor potentiometer
Alternatively to the input signal nMainSetValue_a (or nAuxSetValue_a in case of local setpoint selection), the speed
setpoint can also be generated via a motor potentiometer function.
• In the Lenze setting, the motor potentiometer function is deactivated.
• Activation is possible via C00806
or via the bMPotEnable input.
• The behaviour of the motor potentiometer during switch-on of the drive system can be selected in C00805
.
• For a detailed functional description see the L_MPot
FB.
bMPotEnable
BOOL
Activating the motor potentiometer function
•This input and C00806
are OR'd.
TRUE The motor potentiometer function is active; the speed setpoint can
be changed via the bMPotUp and bMPotDown control inputs.
bMPotUp
BOOL
Increasing the speed setpoint
TRUE Approach the upper speed limit value set in C00800
with the
acceleration time set in C00802
.
bMPotInAct
BOOL
Activating the inactive function
TRUE The speed setpoint behaves according to the inactive function set in
C00804
.
• In the Lenze setting, the speed setpoint is maintained.
bMPotDown
BOOL
Decreasing the speed setpoint
TRUE Approach the lower speed limit value set In C00801
with the
deceleration time set in C00803
.
Process controller
• In the Lenze setting, the process controller is deactivated.
• The activation is executed by selecting the operating mode in C00242
.
• For a detailed functional description see FB L_PCTRL
.
bPIDEnableInfluenceRamp
BOOL
Activate ramp for influencing factor
FALSE Influencing factor of the PID controller is ramped down to "0".
TRUE Influencing factor of the PID controller is ramped up to the value
nPIDInfluence_a.
bPIDIOff
BOOL
Switch off the I-component of the process controller
• In conjunction with the operating mode set in C00242
(Lenze setting: "Off").
TRUE I-component of the process controller is switched off.
nPIDVpAdapt_a
INT
Adaptation of gain Vp set in C00222 in percent
• Scaling: 16384 ≡ 100 %
• Internal limitation to ± 199.99 %
• Changes can be done online.
nPIDSetValue_a
INT
Sensor and process setpoint for operating modes 2, 4 and 5
• Scaling: 16384 ≡ 100 %
• Internal limitation to ± 199.99 %
nPIDActValue_a
INT
Speed or actual sensor value (actual process value)
• Offset and gain for this input signal can be set in C00698
and C00672.
• Scaling: 16384 ≡ 100 %
• Internal limitation to ± 199.99 %
nPIDInfluence_a
INT
Limitation of the influencing factor in percent
• The influence factor of the PID controller can be limited to a certain value (-
199.99% ... + 199.99%) via nPIDInfluence_a.
• Scaling: 16384 ≡ 100 %
• Internal limitation to ± 199.99 %
