(5) Behavior of SOL1 and SOL2
SOL1
Output works by the Input of
1ST STAGE
. When
1ST STAGE
Input is open,
SOL1
Output also becomes open if it is before the start of a weld sequence. After
the start of a sequence, even if
1ST STAGE
Input is open,
SOL1
Output keeps
closed until the sequence comes to an end.
When using
SOL1
,
1ST STAGE
Input allows
SOL1
to adjust a squeeze location.
After the input of
1ST STAGE
, weld current can be supplied by
2ND STAGE
Input.
SOL2
Output works by the Input of
2ND STAGE
and is closed from SQ to HO.
Symbol:
SQ: Squeeze Time
RC: Resistance Pre-check Time
CP: Resistance Judgment Time (1ms) U1: Upslope 1 Time
W1: 1st Weld Time
D1: Downslope 1 Time
CO: Cool Time
U2: Upslope 2 Time
W2: 2nd Weld Time
D2: Downslope 2 Time
HO: Hold Time
a: When
1ST STAGE
Input is open before the start of a weld sequence,
SOL1
Output also becomes open
b: Once the sequence is started,
SOL1
Output keeps closed until HO is
completed even if
1ST STAGE
Input is made open.
