VLT ® 2900 Series 0.02 - 3600.00 sec. 3.00 sec (VLT 2903-2975) 10.00 sec (VLT 2980-2982) Function: See description of parameter 207 Ramp-up time 1 . Description of choice: Set the required ramp-up time. Shift from ramp 1 to ramp 2 by activating Ramp 2 via a digital input. 0.02 - 3600.00 sec 3.00 sec (VLT 2903-2975) 10.00 sec (VLT 2980-2982) The ramp-up time is the acceleration time from 0 Hz to the rated motor frequency f M,N (parameter 104 Motor frequency, f M,N ). It is assumed that the output current will not reach the current limit (set in parameter 221 Current limit I LIM ). 0.02 - 3600.00 sec. 3.00 sec (VLT 2903-2975) 10.00 sec (VLT 2980-2982) Function:
See description of parameter 208 Ramp-down time 1 . Programming Description of choice: Set the required ramp-down time. Shift from ramp 1 to ramp 2 by activating Ramp 2 via a digital input. 0.02 - 3600.00 sec. 3.00 sec (VLT 2903-2975) 10.00 sec (VLT 2980-2982) Set the required ramp-up time. Function: The jog ramp time is the acceleration/deceleration time from 0 Hz to the rated motor frequency f M,N (pa- rameter 104 Motor frequency, f M,N ). It is assumed that the output current will not reach the current limit (set in parameter 221 Current limit I LIM ).
0.02 - 3600.00 sec 3.00 sec (VLT 2903-2975) 10.00 sec (VLT 2980-2982) The ramp-down time is the deceleration time from the rated motor frequency f M,N (parameter 104 Motor fre- quency, f M,N ) to 0 Hz, provided no overvoltage arises in the inverter because of generating operation of the motor. Set the required ramp-down time. = factory setting, () = display text, [] = value for use in communication via serial communication port MG.29.A3.02 - VLT ® is a registered Danfoss trademark 31 209 Ramp-up time 2 (ramp up time 2) Value: 207 Ramp-up time 1 (ramp-up time 1) Value: 210 Ramp-down time 2 (RAMP DOWN TIME 2) Value: Function: 211 Jog ramp time (jog ramp time) Value: Description of choice:
