IS-300CA INVERTER POWER SUPPLY

NOTES:
•
When the next start signal is received while the monitor error is displayed on the Pendant, the
CAUTION signal is turned OFF and the previous screen is displayed. At this time, the data is
transferred to the Pendant from the Power Supply. The start signal is not received while the data is
transferred. (Ta: 40ms max. in the figure above.) When the monitor error is displayed, input the start
signal more than (Ta) time.
•
When the sequence ends, the END signal will be present after HOLD .
To make the cycle time faster, lower the output time of END signal. (Set in 10ms increments,
≥
10ms.)
•
When the MONITOR screen is displayed, the monitor data is transferred to the Pendant simultaneously
with the END signal output (transmission time Tb1). The monitor data is not transferred when the
screen other than
MONITOR
screen is displayed.
The next Start signal is not received while the monitor data is transferred. Also, on every screen,
the data is transferred to the Pendant from the Power Supply to display the monitor error when the
monitor data is beyond / below the upper / lower limit (data communication time Tb2).
The data communication time at end “Tb” is shown in the table below.
MONITOR ERROR
OCCURS
MONITOR ERROR
DOES NOT OCCUR
MONITOR screen Tb1: 164ms max.
Tb1+Tb2+α:
280 (438) ms max.
Screens other than
MONITOR screen
0ms
Tb2:
113 (144) ms max.
*
Time in ( ) is the time with RS-232C communication.
•
When the RS-232C external communication function is set to the single-directional
communication mode (
MODE SELECT
Screen), the monitor data is transferred to the host
computer after the completion of welding (transmission time
Tc1
).
Also, when the monitored value is outside the upper/lower limit on the
MONITOR SET
screen, the
monitor error code is transferred to the host computer (transmission time
Tc2
). The Start signal
will not be received while transmitting data.
To make start time faster, set the external communication function to OFF.
Shown below is the data transmission time
Tc1
and
Tc2
when the communication speed is 9600
bps. When the communication speed is 19200bps or 38400bps, the transmission time will be
shorter.
•
Data transmission time when the communication speed is 9600 bps
Tc1 132ms max.
Tc2 42ms max.
