CHAPTER 3: USING PROGRAMMING FUNCTIONS
IS-300CA INVERTER POWER SUPPLY
990-418 3-53
When VALVE MODE is 2 VALVE
Set the valve # in the range of 1 to 2.
SOL1 and SOL2, and EX SOL1 to EX SOL2 on the I/O terminal block are used for valve output.
VALVE #1: SOL1, SOL2
VALVE #2: EX SOL1, EX SOL2
k. FORGE VALVE #
The forge force function can be used.
The forge valve can be used at the given timing (the head force can be changed) except the valve
selected in VALVE #.
Select a valve to output the forge force.
Operation differs according to the VALVE MODE setting on the MODE SELECT screen.
When VALVE MODE is 1 VALVE
The forge valve No. is set in the range of 1 to 4.
Do not set the same number as that used for the valve No.
EX SOL1 to EX SOL4 on the I/O terminal block are used for valve output.
FORGE VALVE #1: EX SOL1 FORGE VALVE #3: EX SOL3
FORGE VALVE #2: EX SOL2 FORGE VALVE #4: EX SOL4
When VALVE MODE is 2 VALVE
FORGE VALVE # is fixed to 4.
EX SOL4 on the I/O terminal block is used for valve output.
Valid only when FORGE MODE is ON.
l. CHAINING
Used for the chaining function.
The welding is performed with SCHEDULEs with the chaining setting in order while the start
signal (1ST and 2ND) is input.
All values of the chained schedules must be entered, especially the turns ratio, to ensure proper
weld output.
For example, when CHAINING for SCHEDULE 1, 2, 5, and 6 are ON, the welding is performed
sequentially in order of SCHEDULE 1 → SCHEDULE 2 → SCHEDULE 5 → SCHEDULE 6
by the start signal (1ST and 2ND) input.
m. SUCCESSIVE
Used for the successive function.
The welding is performed with SCHEDULEs with the successive setting in order each time the
start signal (1ST and 2ND) is input.
