Siemens SINAMICS G115D User Manual

Parameter Description Setting
p1120[0...n] Ramp-function generator, ramp-
up time [s]
The ramp-function generator ramps-up the speed
setpoint from standstill (setpoint = 0) up to the
maximum speed (p1082) in this time.
Factory setting: 1
p1121[0...n] Ramp-function generator, ramp-
down time [s]
Sets the ramp-down time for the ramp-function
generator.
Factory setting: 1
p1135 OFF3 ramp-down time [s] Sets the ramp-down time from the maximum
speed down to zero speed for the OFF3 command.
Factory setting: 0
Changing the ramp-up and ramp-down times in operation
The ramping up and down time of the ramp-function generator can be changed during
operation. The scaling value can come, e.g. from the 󹪝eldbus.
Preconditions
• You have commissioned the communication between the converter and the control system.
• Free telegram 999 has been set in the converter and in your higher-level control system.
Expanding or freely interconnecting telegrams (Page154)
• The control sends the scaling value to the converter in PZD3.
Procedure
1. Set p1138 = 2050[2].
This means that you have interconnected the scaling factor for the ramp-up time with PZD
receive word3.
2. Set p1139 = 2050[2].
This means that you have interconnected the scaling factor for the ramp-down time with PZD
receive word3.
The converter receives the value for scaling the ramp-up and ramp-down times via PZD
receive word3.

p1139[0...n] CI: Ramp-function generator ramp-
down time scaling
Sets the signal source for scaling the ramp-down
time of the ramp-function generator.
Factory setting: 1
