About Step 1: The assumption is made that the checks on the drive equipment, mounting and installation, as outlined in Chapters 6.2 through 6.4, have already been performed. This is generally the case with an already constructed and operating machine. About Steps 2 through 4: INDRAMAT’s drives offer definite advantages when searching for and eliminating problems. Long-term searches for problems in individual units and repairing the drive components of the individual machines are not acceptable because of the loss in production that this loss in time represents. The diagnostic displays and the message signals at the interfaces between drive and controller (terminal strip on the drive module) make a to-the-point and effective problem search possible. The exchange of individual compact drive components such as supply module, drive amplifier, motor or cable permit a speedy and problem-free elimination of the problem and resumption of operation without lengthy mounting and adjustment work. Programming modules MOD, optimized and ready-to-use from the factory, make an adjustment-free exchange possible.

Construction of the monitoring system within the modules

In the event of a problem in the drive system, the ready-to-operate command is lifted and the at-zero-potential ready-to-operate contact Bb1 in the supply module and Bb in the drive module open. The opening of the Bb1 contact must achieve, via the controller, – an immediate mains separation (mains contactor must release), – the drive’s mechanical brakes, (if present), snap in, – the activation of the link circuit short circuit as an additional electrical brake for the MAC servo motors, (if present). An overview in Figure 72 of the internal drive monitor offers insight into the effect of an internal fault. A fault in the supply unit is signalled to the drives via the internal „UD“ message X1.1 of the plug-in terminal X1 between the modules. The connected drives decelerate to speed zero and are then subsequently locked (after approximately 300 ms), i.e., switched torque-free.

The same thing occurs with a fault in the servo drive module. The drive fault is then signalled to the supply module via the BB return signal cable X1.2 of the bus X1, where it permits the Bb1 signal contact to drop.
