4.5 Electrical installation
4.5.1 General notes
• Make sure the leads/cables leading to the motor can handle the maximum motor current.
• Do not exceed the peak current of the motor. Peak current is 1.41 × RMS current.
• An emergency stop is recommended to reduce the chance of a crushing hazard.
• Never work on the linear system or the wiring with the power switched on.
4.5.2 Electrical connections
The linear system motor is always supplied with ying lead wires that are attached to the stepper motor.
These lead wires are used to connect to the stepper motor and drive the carriage. Depending on the
conguration, motors have various wire gauge sizes. The standard gauges are outlined in the table below.
