Automation may recommend that the same type of shielded cable specified for the AC motors be used between the drive and transformer Check the individual user manuals or system schematic note sheets for specific additional requirements in these situations The majority of recommendations regarding drive cable address issues caused by the nature of the drive output A PWM drive creates AC motor current by sending DC voltage pulses to the motor in a specific pattern These pulses affect the wire insulation and can be a source of electrical noise The rise time amplitude and frequency of these pulses must be considered when choosing a wire cable type The choice of cable must consider 1 The effects of the drive output once the cable is installed 2 The need for the cable to contain noise caused by the drive output 3 The amount of cable charging current available from the drive 4 Possible voltage drop and subsequent loss of torque for long wire runs Keep the motor cable lengths within the limits set by the drive s user manual Various issues including cable charging current and reflected wave voltage stress may exist If the cable restriction is listed because of excessive coupling current apply the methods to calculate total cable length as shown in Figure 1 11 If the restriction is due to voltage reflection and motor protection tabular data is available Refer to Appendix A for exact distances allowed gt
