If the set-point value zero switch is dropped, then a master controller must guarantee the shutting down of the drives with a closed NCB bridge. This means that the master controller evaluates the UD contact and shuts the drives down when the contact opens. Otherwise,switching the power off means that there will be an uncontrolled slowing down of the drives.
Do not use the NCB bridge in digital drives which have a SERCOS Interface. The programmable fault response of digital drives makes a position-controlled shutdown without the NCB bridge possible. The NCB bridge blocks the message to the drives that there is a fault in the power supply.
The NCP451 is a very low Ron MOSFET controlled by external logic pin, allowing optimization of battery life, and portable device autonomy. Indeed, due to a current consumption optimization with NMOS structure, leakage currents are eliminated by isolating connected IC on the battery when not used. Output discharge path is also embedded to eliminate residual voltages on the output rail. Proposed in a wide input voltage range from 0.75 V to 5.5 V, in a small 0.9 x 1.4 mm WLCSP6, pitch 0.5 mm. Features • 0.75 V – 5.5 V Operating Range • 12 m N MOSFET from 3.6 V to 5.5 V • 13 m N MOSFET from 1 V to 3.3 V • DC Current Up to 3 A • Output Auto−Discharge • Active High EN Pin • WLCSP6 0.9 x 1.4 mm • These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant
Extensive searches and repairs are unacceptable because of the production losses which these represent. The design of INDRAMAT AC drives makes a complete exchange of the individual units without weary adjustment work possible. This means that any service due to problems restricts itself to locating the problem either in the motor, the supply module or the drive module. Then it limits itself to a complete replacement of the entire problem unit. 6.1. Locating the problem Problems with axes movements are generally caused by the interaction of the CNC controller, supply and drive modules, motor, mechanical and position measurements, or the faulty adjustment of the individual components to each other. The KDV 4 is equipped with an extensive diagnostic system so that any problem can be quickly located.The auto−discharge is activated when EN pin is set to low level (disable state). The discharge path (Pull down NMOS) stays activated as long as EN pin is set at low level and VIN > 0.75 V. In order to limit the current across the internal discharge N−MOSFET, the typical value is set at RDIS. CIN and COUT Capacitors IN and OUT, 1 F, at least, capacitors must be placed as close as possible the part to for stability improvement.
