MEA-100B
8. Stepper-Up Function
8-3
(3) Stepper-Up (-Down) Rate Setting
ATTENTION
Set the value of “the welding current x the stepper-up rate” so that it does not
exceed the following value:

The set maximum current (6. (3)) in the secondary constant-current control

99.9% in the power supply voltage fluctuation compensation control
When the value over the maximum current is set, the fault code [E09: STEPUP
RATE TROUBLE] is given at the input of the start signal. (For faults, see 12.)

Press the [MENU] key to go to the Stepper-Up Rate Setting Screen.

Move the cursor to "e" and select the welding head from SOL1 and SOL2.

Move the cursor to "a"–"d" and set the stepper-up rates for steppers 2–5.
Set the rate in a percentage to the set value of the welding current expressed as
100% (See 7. (2)). Setting range is 50% to 150%.
a: Up rate for Stepper 2 b: Up rate for Stepper 3
c: Up rate for Stepper 4 d: Up rate for Stepper 5
