8119 AUTOCHNG LEVEL 0.0…100.0%
Sets an upper limit, as a percentage of output capacity, for the
autochange logic. When the output from the PID/PFA control block
exceeds this limit, autochange is prevented. For example, use this
parameter to deny autochange when the Pump-Fan system is operating
near maximum capacity.
Autochange overview
The purpose of the autochange operation is to equalise duty time
between multiple motors used in a system. At each autochange
operation:
• A different motor takes a turn connected to the ACH550 output – the
speed regulated motor.
• The starting order of the other motors rotates.
The Autochange function requires:
• external switchgear for changing the drive’s output power
connections.
• parameter 8120
INTERLOCKS = value > 0.
Autochange is performed when:
• The running time since the previous autochange reaches the time set
by parameter 8118
AUTOCHNG INTERV.
• the PFA input is below the level set by parameter 8119
AUTOCHNG
LEVEL.
