L_MFail inputs
Function
nAdapt_a
Dynamic adaptation of the proportional gain of the DC-bus voltage controller.
• Input not interconnected
Adaptation = 0 %.
nConst_a
Proportional gain of the DC-bus voltage controller
• Input with
nPos100_a
constant interconnected
proportional gain = 100 %.
nDCSet_a
Voltage setpoint on which the DC-bus voltage is to be kept.
• The voltage setpoint has to be set in the "free parameter"
.
nNset_a
Speed setpoint path (output: nNOut_a)
bFault
Activating the mains failure control
Procedure of the mains failure control (
bReset
Reset mains failure control
• The free
bFreeIn2
input of the application block used in the example can be e.g.
connected to a digital input on I/O level.
nThreshold_a
Restart threshold
• The restart threshold (at first approx 2 %) has to be set in the "free parameter"
.
nNAct_a
Comparison value for the restart threshold
• Comparison value is the actual speed value
nSet_a
Speed starting point for the deceleration
• Speed starting point is the actual speed value
nDCVoltAct_a
Actual DC-bus voltage
