Basic Infeed Open-Loop Control - Siemens SINAMICS S120 Function Manual

Remedial measures:
● activate the V
– Vector control: p1240 = 1 (factory setting)
– Servo control: p1240 = 1
– V/f control: p1280 = 1 (factory setting)
● Inhibit V
– Vector control: p1240 = 0
– Servo control: p1240 = 0 (factory setting)
– V/f control: p1280 = 0
● Activate the V
– Vector control: p1240 = 4 or 6
– Servo control: p1240 = 4 or 6
– V/f control: p1280 = 4 or 6
Unexpected motion of individual drives
If several Motor Modules are supplied from one infeed unit, then if the V
incorrectly parameterized, individual drives can accelerate in an uncontrolled fashion -
which can lead to death or severe injury.
• Only activate the V
• Inhibit this function for all other Motor Modules, or set this function to monitoring only.
2.3.1

Basic Infeed open-loop control

The Basic Line Module can be controlled via a BICO interconnection, e.g. using terminals or
fieldbus. The operating status is indicated on the operating display r0002. The missing
enable signals for operation (r0002 = 00) are mapped in parameter r0046. The EP terminals
(enable pulses) must be connected in accordance with the manual of the corresponding
power units.
Acknowledging faults
Faults that are still present but the causes of which have been rectified can be
acknowledged using a 0/1 edge at the "1st acknowledge faults" signal (p2103).
