BN GY BK RD WH 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.228) . The records are controlled via the PROFIBUS DP or PROFINET interface. Programming via field bus: To drive the motor and to integrate into the „Step 7“ / „TIA portal“ software, a library with a function block (FB) and programming examples are included in the scope of delivery. The documentation for the programming is available on request. Input Function Information In1 (24V) Release Permanent signal In2 (24V) Start Positive edge starts selected set In3 (24V) Quick stop Do not switch from outside (internal use) In4 (24V) Reference Do not switch from outside (internal use) In5 (24V) + In6 (0V) Open Record 1 In5 (0V) + In6 (24V) Close Record 2 In5 (24V) + In6 (24V) Intermediate position Record 3 (Standard = 1/2 stroke) Note for control via PROFINET: If the record selection and start functions are carried out via commands 286 and 287 via PROFINET, the input functions „Start“ (In2) and „Record selection x“ (In5 and In6) must not be set or used, as the input functions are prioritised over the PROFINET commands. 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.279) .
