Siemens SINAMICS G220 - Example for Setting Fixed Speed Setpoint

c1076[0...n] Supplementary setpoint scaling 

14.9.4 Example for setting 󹪝xed speed setpoint
Overview
The example shows how to select two 󹪝xed speed setpoints directly.
The motor should run at di󹪜erent speeds as follows:
• The signal at digital input0 switches on the motor and accelerates it to 300rpm.
• The signal at digital input1 accelerates the motor to 2000rpm.
• With the signals at both digital inputs, the motor accelerates to 2300 rpm.
Settings
Table 14-68 Setting a 󹪝xed speed
Parameter Description
p1001 = 300.000 Fixed speed setpoint 1
p1002 = 2000.000 Fixed speed setpoint 2
r0840 = 722.0 ON/OFF1: Switch on motor with digital input0
r1070 = 1024 Main setpoint: Interconnect main setpoint with 󹪝xed speed setpoint.
r1020 = 722.0 Fixed speed setpoint selection bit 0: Interconnect 󹪝xed speed setpoint1
with digital input0 (DI0).
r1021 = 722.1 Fixed speed setpoint selection bit 1: Interconnect 󹪝xed speed setpoint2
with digital input1 (DI1).
p1016 = 1 Fixed speed setpoint mode: Choose direct selection of 󹪝xed speed set‐
points.
