Connecting the components
Please note the following:
Notice
Use only shielded cable and make sure that the shield is connected to the
metal or metal plated connector casing on the control side. For the purpose of
isolating the analog setpoint signal from low-frequency interference, we
recommend not to ground the shield on the drive side.
The preassembled cable offered as accessories provides optimum protection
against interference.
General procedure:
Proceed as follows to connect the individual components:
1. Connect the cables to the components as shown in Fig. 2–3.
2. Fix the sub-D connector in place using the knurled screws.
