Control via state machine
In the operation mode “control via state machine” (parameter
Local/Remote
412 =
1), the frequency inverter is controlled via the
Control word.
State transition 4 to state “Operation enabled” is only possible when:
−
In Motion control configuration (parameter
Configuration
30 = x40) digital input
S1IND (= STOA AND STOB) is set.
−
In other control configurations (parameter
Configuration
30 ≠ x40) the controller
release via STOA and STOB and one of the digital inputs S2IND or S3IND is set.
(Typical S2IND = start clockwise, S3IND = start anticlockwise)
Object
is relevant to the inverter whenever parameter
Lo-
cal/Remote
412 is set to 1 (remote state machine).

Bits 9 … 15 are used depending on the configuration and on
Control word bits 4, 5, 6 operation mode specific and bit 8 halt are used in motion con-
trol configurations (Parameter
