q) Logic for the Brake Activation when DOx or Relay = 30 or 31
NOTES!
1) To release the brake (transition from NC to NO) both comparisons are performed Is > Ix, Is > Imr. At the same
time, the inverter shall receive a Start/Stop command in the "Run" state and with no error.
2) To activate the brake (transition from NO to NC) the comparison N > Nx is performed.
3) If P202 = 4 (Vector with Encoder), the brake is not activated when the speed crosses zero at the reversing of the
direction of rotation.
