☆This switching is done when acceleration/deceleration 2 (AD2) is assigned to the R terminal (when H (input terminal selection 2) is set to 5 (acceleration/deceleration 2)), using the multi- function programmable input terminal function.

In this case, set EOQF to 0 (terminal block).

No signal for switching to acceleration/deceleration 2 is set by default. If necessary, assign function 5 (AD2) to an unassigned terminal, using the input terminal selection function.

6.14Protection functions

6.14.1Current stall setting

H

:Stall prevention level

• Function

If a current exceeding the level specified with H, the stall prevention function is activated to decrease the output frequency.

When specifying a value larger than 100 (%), set also the VMT parameter (motor electronic thermal protection level) properly.

■Parameter setting

Title	Function	Adjustment range	Default setting
H	Stall prevention level	30～199 (%)	150
		200: Invalid

[Message displayed along with an QE alarm]

If an QE alarm goes off (if a current exceeding the stall prevention level), the output frequency displayed will change and the “E” on the left of it will blink.
