FUNCTION C
ODES
[ 2 ] Cancel regular switching operation
Operating time is counted during which there are no changes in the number of motors. When
this count reaches the specified motor operation switching time (J436), regular switching
occurs. Clearing this count by changing the regular switching time clearing command
“MCLR” from ON to OFF cancels this regular switching. While the switching warning signal
“MCHG” is being output, the regular switching time clearing command “MCLR” can be
turned from ON to OFF to cancel regular switching.
• When the motor regular switching time clearing command "MCLR" remains
tuned on continually, the time in which the number of operating motors remains
unchanged is always cleared, which prevents motor regular switching from
running.
[ 3 ] Regular switching via input terminal
Even if there are no changes in the number of motors and the specified motor operation
switching time (J436) is not reached, changing the pump control switching command
“PCHG” from ON to OFF allows regular switching to be performed. In this case, the count of
the time during which the number of motors in operation remains unchanged is cleared.
