− if a pulse encoder is used make sure that pulse encoder's auxiliary voltage connection corresponds to its
voltage and that the channel connection corresponds to correct direction of rotation,
− check that the shielding of the pulse encoder's cable is connected to the TE bar of the DCS550,
− if an analog tacho is used make sure that it is connected to the proper voltage input at the SDCS-CON-F:
X3:1 - X3:4 (90 - 270 V)
X3:2 - X3:4 (30 - 90 V)
X3:3 - X3:4 (8 - 30 V)
− for all other cables make sure that both ends of the cables are connected and they do not cause any
damage or danger when power is being switched on
Measuring the insulation resistance of the motor cables and the motor:
isolate the motor cables from the drive before testing the insulation resistance or voltage withstand of the
− cables or the motor,
Instructions how to measure the insulation resistance
− measure the insulation resistance between:
1. + cables and PE,
2. - cables and PE,
3. armature cables and field cables,
4. field - cable and PE,
5. field + cable and PE,
− the result should be MΩs
Setting of Jumpers:
− The boards of the DCS550 include jumpers to adapt the boards to different applications. Check the
position of the jumpers before connecting voltage. For specific jumper settings, see chapter Electronics.
Check following items for each drive and mark the differences in the delivery documents:
− motor, analog tacho or pulse encoder and cooling fan rating plates data,
− direction of motor rotation,
− maximum and minimum speed and if fixed speeds are used,
− speed scaling factors:
− e.g. gear ratio, roll diameter,
− acceleration and deceleration times,
− operating modes:
− e.g. stop mode, E-stop mode,
− the amount of motors connected
