P1140[0...2] BI: RFG enable - 1 T - CDS U32 /
Bin
3
Defines command source of RFG enable command (RFG: ramp function generator). If binary input is
equal to zero then the RFG output will be set immediately to 0.
P1141[0...2] BI: RFG start - 1 T - CDS U32 /
Bin
3
Defines command source of RFG start command (RFG: ramp function generator). If binary input is equal
to zero then the RFG output is held at its present value.
P1142[0...2] BI: RFG enable setpoint - 1 T - CDS U32 /
Bin
3
Defines command source of RFG enable setpoint command (RFG: ramp function generator). If binary
input is equal to zero, the RFG input will be set to zero and the RFG output will ramp-down to zero.
r1170 CO: Frequency setpoint
after RFG [Hz]
- - - - - Float 3
Displays overall frequency setpoint after ramp generator.
P1175[0...2] BI: Dual ramp enable - 0 T - CDS U32 /
Bin
3
Defines command source of dual ramp enable command. If binary input is equal to one, then the dual
ramp will be applied. This works as follows:
1. Ramp-up:
– Inverter starts ramp-up using ramp time from P1120
– When f_act > P2157, switch to ramp time from P1060
2. Ramp-down:
– Inverter starts ramp-down using ramp time from P1061
– When f_act < P2159, switch to ramp time from P1121
