5.7.9 24V digital outputs
Some versions of the servo-drive/inverter are equipped with a certain number of 24V general-purpose digital
outputs. They are typically used for piloting 24V actuators (such as solenoid valves, relay or contactor coils,
lamps, etc.), or for generating digital signals (for example, for communicating with a PLC).
The following picture shows an example of actuator connection; in most applications, the wiring does not
require a shielded cable, unless it interferes with nearby devices.
If a digital signal must be generated for communicating with another device (such as PLC, shown in the
example), the recommended connection scheme is as follows:
In this case, electrical interference problems are more likely, therefore it is recommended to use a shielded
cable for the connections. The shield must be connected to earth on both sides, preferably with low-
impedance connection, such as a metal cam; the shield is totally ineffective if it is left floating.
5.7.10 Motor brake output
Some versions of the servo-drive/inverter are equipped with a digital output for controlling a 24V motor
brake.
The following picture shows an example of motor brake connection; in most applications, the wiring does not
require a shielded cable, unless it interferes with nearby devices.
