3.5 Setting the limit of motor current
The potentiometer P3 is used to adjust the maximum current of the connected
motor in steps of 100 mA:
P3 at left stop: Motor current 1 A max.
P3 at right stop: Motor current 10 A max.
3.6 Counter-clockwise rotation of motor/motor stop
Input: HE1
To start the counter-clockwise rotation the inputs HE3 (release) and HE4 (quick
stop) must be closed (logical 1). The input HE2 (clockwise rotation) must be
open (logical 0).
The motor starts in counter-clockwise rotation with the ramp adjusted as soon as
the contact HE1 is closed (switched to logical 1). As soon as the contact HE1 is
opened (switched to logical 0) the motor stops corresponding to the ramp setting.
3.7 Clockwise rotation of motor/motor stop
Input: HE2
To start the clockwise rotation the inputs HE3 (release) and HE4 (quick stop)
must be closed (logical 1). The input HE1(counter-clockwise rotation) must be
open (logical 0).
The motor starts in clockwise rotation with the ramp adjusted as soon as the
contact HE2 is closed (switched to logical 1). As soon as the contact HE2 is
opened (switched to logical 0) the motor stops corresponding to the ramp setting.
3.8 Motor quick stop
Input: HE4
In case of a quick stop the motor is stopped immediately without considering the
adjusted stopping ramp. A reclosing interlock is activated.
A quick stop of the motor is performed, if
•
the contact at HE4 is opened (switched to logical 0) or
•
the contacts of the inputs HE1 (counter-clockwise rotation) and HE2
(clockwise rotation) are closed simultaneously (switched to logical 1) or
•
the maximum motor current is exceeded or
