- Auxiliary contact HI11-P1/P3E 061813 applicable to
K2. Auxiliary early open contact
Examples:
- Auxiliary contact HIV in automatic switches NZM1, 2
Note. Observe that having the main key - S1 closed, although the power contactor - KM1 is open, the internal
auxiliary power supply of the XPS remains connected through its connector X3 to feed the control circuits of the
drive.

Diagram of the maneuver
Important. The relay - KA3 uses delayed deactivation for contactor - KM1 (t seconds) in order to be able to keep it
closed long enough to return to mains the excess energy generated while braking the motor. Make sure that the
delay t programmed at relay - KA3 is slightly longer than the braking time until the motor comes to full stop. See also
parameter GP9 in the «man_dds_soft.pdf» manual.
