command
Meaning
• This relay turns on when "current value of
CH2 = coincidence output No.2 point
setting value" is met.
• This relay is turned off by turning on CH2
coincidence signal No.2 reset command.
• This relay turns on when "current value of
point (No.2) or CH2 < coincidence output No.2 point
greater setting value" is met.
• This relay turns off when "current value of
CH2 ≥ coincidence output No.2 point
coincidence point
(No.2) setting value" is met.
• This relay turns on when a preset request
by phase Z (preset) terminal of CH2 is
detected.
• This relay is turned off by turning on CH2
external preset (phase Z) request detection
clear command.
• This relay turns on if the CH2 error occurs.
• This relay turns off when an error cause is
removed and CH2 error reset command is
turned on.
• This relay turns on if a warning occurs in
CH2.
• This relay turns off when a warning cause
is removed and CH2 error reset command
is turned on.
• This relay is turned on to reset CH2
counter value coincidence No.1.
• The command is valid while this relay is on.
• The on time must be held for at least 2ms.
• This relay is turned on to reset CH2
counter value coincidence No.2.
• The command is valid while this relay is on.
• The on time must be held for at least 2ms.
• This relay is turned on to perform
coincidence output from CH2 coincidence
output No.1 and CH2 coincidence output
No.2 terminals.
• The command is valid while this relay is on.
• This relay is turned on to preset the counter
value.
• The command is valid at the rise of this
relay (off → on).
• The on and off time must be held for at
least 2ms.
• This relay is turned on to count down
pulses.
• The command is valid while the Pulse input
mode is either 1-phase multiple of n or 1-
phase multiple of n (A phase only).
• The command is valid while this relay is on.
