Ballast connections wire No. 3 and 4 insulate if not used. No voltage counter, otherwise the servo drive will be damaged! Quick stop function servomotor Sensor reference Note: Connection to the safety switch and the optional position sensors are not detailed in this electrical connection plan. The software ServoLink for the adaptation of the driving data sets and motor parameters is available together with the programming cable WP1 as an accessory (see p.178) . The records are controlled via the PLC interface. Quick stop function servomotor: When the MecLock protection system is activated, the closing door leaf or protective field is stopped mechanically without overrun. Since an immediate stop of the electric drive is not possible as quickly as with the mechanical MecLock protection system, slip or overload clutches are used to decouple the drive train from the locked door leaf or protective field and to avoid damage to the gear unit and servo motor. The quick stop function, which is triggered by a ground circuit or an actuated band switch, then automatically stops the still running servomotor and triggers a homing run. Sensor reference: The safeguard references itself automatically via the built-in reference sensor if the quick stop input becomes “Low”, a previous error has led to the loss of the reference position or the power supply of the logic part of the servomotor has been interrupted. Additional tubular fixed resistor (optional): For very heavy safeguards and very short down- times, a tubular fixed resistor may need to be installed (see p.231) .
