ACH550 User's Manual
Starting order
counter
The operation of the
starting order
counter:
• The relay output
parameter
definitions
(1401…1403 and
1410…1412)
establish the initial
motor sequence.
(The lowest
parameter number
with a value 31
(PFA) identifies the
relay connected to
1PFA, the first motor, and so on.)
• Initially, 1PFA = speed regulated motor, 2PFA = 1st auxiliary motor,
etc.
• The first autochange shifts the sequence to: 2PFA = speed regulated
motor, 3PFA = 1st auxiliary motor, …, 1PFA = last auxiliary motor.
• The next autochange shifts the sequence again, and so on.
• If the autochange cannot start a needed motor because all inactive
motors are interlocked, the drive displays an alarm (2051,
PFA
INTERLOCK
).
• When the ACH550 power supply is switched off, the counter
preserves the current Autochange rotation positions in permanent
memory. When power is restored, the Autochange rotation starts at
the position stored in memory.
• If the PFA relay configuration is changed (or if the PFA enable value
is changed), the rotation is reset. (See the first bullet above.)
