Position Tol.
The tolerance is defined here so that the supply can be switched off
when the end position is reached. When the door reaches its position
tolerance, the motor supply is canceled and the “Open“ door position
relay and “Closed“ door position relay are activated.
Example: When the fully open position is set to 700 and the position
tolerance is set to 5, the motor voltage is switched off when 695 is
reached and the door opening relay switches.
Relay Tol.
This sets the tolerance within which the door position relays remain
activated.
Example: If the fully open position is set to 700, the position tolerance
is set to 5 and the relay tolerance is set to 30, then the “End position
OPEN“ relay is activated when 695 is reached. The relay drops out
when the door closes and reaches position 670.
DC Brake Cur.
DC Brake is used to conduct direct current into the motor windings when
the current door position is within the position tolerance at the end of the
movement, i.e. fully open or fully closed.
The DC brake helps to stop the door before the motor brake is activated.
For freezing areas, the DC brake can be set to prevent the drive from
freezing. The DC braking time should be set to 100 to maintain constant
DC current to the motor. DC Brake Cur. should be selected to provide the
correct temperature.
DC Brake Time
F. Close
Time during which the door is kept closed after the fully closed position
has been reached.
F. Open
Time the door is kept open after reaching the fully open position.
