• When NORMAL, NORMAL TRACE or SINGLE TRACE is set for MODE in
the SYSTEM SETUP (1) screen (Refer to Chapter 8, “n-1. SYSTEM SETUP
(1) Screen.”)
1) CURR NG: Current error
Output if the currents (peak and RMS) exceed the upper limits or fall below the
lower limits.
2) VOLT NG: Voltage error
Output if the voltages (peak and RMS) exceed the upper limits or fall below the
lower limits.
3) TIME NG: Current flow time error
Output if the current flow time exceeds the upper limit or fall below the lower
limit.
4) TIME TP NG: Current flow time TP error
Output if the current flow time TP falls below the lower limit or fall below the
lower limit.
5) TIME TH NG: Current flow time TH error
Output if the current flow time TH falls below the lower limit or fall below the
lower limit.
6) FL TIME NG: Current flow time (including fall time) error
Output if the current flow time (including fall time) exceeds the upper limit or
falls below the lower limit.
7) POWER NG: Power error
Output if the power exceeds the upper limit or falls below the lower limit.
8) RESIS NG: Resistance error
Output if the resistance exceeds the upper limit or falls below the lower limit.
9) DIST NG: Displacement error
*1
Output if the displacement exceeds the upper limit or falls below the lower
limit.
10) FORCE NG: Force error
*1
Output if the force exceeds the upper limit or falls below the lower limit.
11) EXT NG: External voltage or current input error
*1
Output if the external ±10 V voltage inputs or the external 4 to 20 mA current
input exceeds the upper limit or falls below the lower limit.
12) NO CURR: Lack-of-current error
Output if lack of current occurs. (The NO CURR signal input terminal on the
external input connector must be used.)
13) NG: Error
Output if an upper/lower limit, overrange, impulse, lack-of-current, or parity
error occurs.
14) GOOD: Normal
Output when the measured value falls within the upper and lower limits, with
current flowing properly.
15) PREDIST NG: Displacement before welding error
*1
Output when the displacement before a welding start exceeds the upper limit
or falls below the lower limit.
16) PREFORCE NG: Force before welding error
*1
Output when the force before a welding start exceeds the upper limit or falls
below the lower limit.
