How to parameterize SPFC control
1. Set PFA reference steps (parameters
) if needed.
2. Set PFA start and stop frequencies (parameters
3. Set PFA auxiliary motor start and stop delays (parameters
…
4. Set the number of auxiliary motors (parameter
).
5. Enable Autochange (parameter
). In SPFC control, the parameter only allows
SPFC to use PFA's alternation switchgear box. It is not used as the operating time
interval between the automatic motor changes as in normal PFA application.
6. Autochange level is ignored (parameter
7. Parameterize Interlocks (parameter
8. Set Bypass function if needed (parameter
).
9. Set PFA start delay (parameter
).
10. Enable SPFC. Depending on the application, set parameter
to value 2 (SPFC ACTIVE – SPFC) or value 3 (SPFC + AUTOCHANGE).
Value 1 (ACTIVE): enables normal PFA functionality.
Value 2 (SPFC ACTIVE – SPFC): enables SPFC function with auxiliary motors
running.
Value 3 (SPFC + AUTOCHANGE): enables SPFC function only when auxiliary
motors are not running
11. Set PFA acceleration and deceleration times if needed (parameters
).
12. Autochange enable with a timed function is ignored (parameter
).
13. Set relays in
. (Transistor output TO [parameter
] can be used as an additional relay output, if needed.) Both PFA and
SPFC use these relays. You must set at least as many relays as there are motors
set for SPFC (= the number of auxiliary motors [parameter
] + 1 [speed
regulated motor] when SPFC is used).
14. Set the number of PFA controlled motors in parameter
(= number of PFC
relays in
15. Also set other needed motor dependent parameters, eg
,
.
PFA control and SPFC control default settings have differences in acceleration time
(
), deceleration time (
) and auxiliary motor stop delay (
) parameters.
