P1113[3]

BI: Reverse

CStat: CT
P-Group: COMMANDS
Defines source of reverse command.
Index:
P1113[0] : 1st. Command data set (CDS)
P1113[1] : 2nd. Command data set (CDS)
P1113[2] : 3rd. Command data set (CDS)
Common Settings:
722.0 = Digital input 1 (requires P0701 to be set to 99, BICO)
722.1 = Digital input 2 (requires P0702 to be set to 99, BICO)
722.2 = Digital input 3 (requires P0703 to be set to 99, BICO)
722.3 = Digital input 4 (requires P0704 to be set to 99, BICO)
722.4 = Digital input 5 (requires P0705 to be set to 99, BICO)
722.5 = Digital input 6 (requires P0706 to be set to 99, BICO)
19.B = Reverse via BOP
Dependency:
Active only when P0719 < 10. See parameter P0719 (Selection of command/setpoint source).

CO: Freq. setp. after dir. ctrl.

P-Group: SETPOINT
Displays setpoint frequency after change of direction.
r1119 CO: Freq. setpoint before RFG
P-Group: SETPOINT
Displays output frequency after modification by other functions, e.g.:
- P1110 BI: Inhibit neg. freq. setpoint,
- P1091 - P1094 skip frequencies,
- P1080 Min. frequency,
- P1082 Max. frequency,
- limitations,
- etc.

P1120[3]

Ramp-up time

CStat: CUT
P-Group: SETPOINT
Time taken for motor to accelerate from standstill up to maximum motor frequency (P1082) when no
rounding is used.

Setting the ramp-up time too short can cause the inverter to trip (overcurrent).
Index:
P1120[0] : 1st. Drive data set (DDS)
P1120[1] : 2nd. Drive data set (DDS)
P1120[2] : 3rd. Drive data set (DDS)
Note:
If an external frequency setpoint with set ramp rates is used (e.g. from a PLC). The best way to achieve
optimum drive performance is to set ramp times in P1120 and P1121 slightly shorter than those of the PLC.
Notice:
Ramp times will be used as follows:
- P1060 / P1061 : JOG mode is active
- P1120 / P1121 : Normal mode (ON/OFF) is active
- P1060 / P1061 : Normal mode (ON/OFF) and P1124 is active
