9. It is indispensable to adapt the line by connecting resistors such as those shown below in the differential channels as close as possible to the speed controller The value ofthese resistors must be between 100 and 150 Ohms typically 120 Ohms In cases where the speed controller is installed coupled to an axis control module it is unnecessary to fit resistors as the axis module is normally of low impedance 90 to 370 Ohms The encoder and line resistors must not consume more than 225 mA Cable type Use a cable containing screened twisted pairs Convey both complementary signals through the same screened conductor pair A A B B Vcc Gnd Screening should be electrically continuous from the motor to the controller Ensure electrical continuity when assembling the connector both motor and controller In case of a long length of cable between 50 and 200 m the size of wires on the encoder output must be 2 5 mm beyond 200 m add an independant power supply 56 Available torque Continuous operation For naturally ventilated motors motor cooling is linked to speed This leads to derating for speeds which are below half the nominal speed Transient operation The overtorque depends on the maximum transient current which the speed controller can supply On starting up to 2 In for 0 2 s Overspeed operation The voltage can
