A.1 Parameter list
1256:8 Ramp-function generator ramp-up time
Min Standard
0.0 2.0
0.0 0.0
During ramp-up, the setpoint is increased from zero to the maximum permissible actual speed.
Note:
Max. permissible actual speed for synchronous motors: Minimum from 1.1 (1.05 from SW 7.1
with "SIMODRIVE 611 universal HR", resolver) x P1400 and P1147
Max. permissible actual speed for induction motors: Minimum from P1146 and P1147
Max. permissible actual speed for linear motors: From P1147
refer to the index entry "Ramp-function generator".
1257:8 Ramp-function generator ramp-down time
Min Standard
0.0 2.0
0.0 0.0
During ramp-down, the setpoint is reduced from the maximum permissible actual speed to zero.
Note:
Max. permissible actual speed for synchronous motors: Minimum from 1.1 (1.05 from SW 7.1
with "SIMODRIVE 611 universal HR", resolver) x P1400 and P1147
Max. permissible actual speed for induction motors: Minimum from P1146 and P1147
Max. permissible actual speed for linear motors: From P1147
refer to the index entry "Ramp-function generator".
1259 Torque/power reduction mot./gen. (ARM SRM)
Force/power reduction mot./gen. (SLM)
Min Standard
0 0
... defines if the torque/power de-rating or force/power de-rating depends on whether the drive
is motoring/generating.
Bit 0 Torque/power reduction, only when motoring
Bit 0 = 1 Reduction is only effective when motoring
Bit 0 = 0 Reduction is effective when motoring and regenerating
Bit 1 Motoring/regenerating limiting dependent on Nset
Bit 1 = 1 The torque limits when motoring are used if the product of torque and speed
setpoint is positive and the speed setpoint is not equal to 0
Bit 1 = 0 The torque limits when motoring are used if the product of torque and speed
actual value is positive or the absolute speed actual value is less than 10 RPM
P1259 valid for input via PROFIBUS and analog input.
Note: refer to the index entry "Torque/power reduction"
1260 i2t limiting, limit current, power section S6
Min Standard
25.0 100.0
... for the i2t power section limiting, it defines the limiting characteristic referred to i-S6.
Note:
I-S6 = P1109 (limiting power section current S6) x P1099 (limiting factor, power section cur-
rents)
refer to the index entry "i2t power section limiting"
