Ramp-Down Time; Bi: Enable Jog Ramp Times - Siemens MICROMASTER 440 Parameter Manual

Parameter Description
P1121[3]

Ramp-down time

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

Index:
P1121[0] : 1st. Drive data set (DDS)
P1121[1] : 2nd. Drive data set (DDS)
P1121[2] : 3rd. Drive data set (DDS)
Notice:
Setting the ramp-down time too short can cause the inverter to trip (overcurrent (F0001) / overvoltage
(F0002)).
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
P1124[3]

BI: Enable JOG ramp times

CStat: CT
P-Group: COMMANDS
Defines source for switching between jog ramp times (P1060, P1061) and normal ramp times (P1120,
P1121) as applied to the RFG. This parameter is valid for normal mode (ON/OFF) only.

P1124[0] : 1st. Command data set (CDS)
P1124[1] : 2nd. Command data set (CDS)
P1124[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)
Notice:
P1124 does not have any impact when JOG mode is selected. In this case, jog ramp times (P1060, P1061)
will be used all the time.
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
