8.2. Protective devices
DANGER
PROTECTIVE DEVICES
The product includes internal protection devices which cut the power
supply to the motor, when activated. Since the motor is no longer
being controlled, driving forces may drop.
• The manufacturer of the system is responsible for complying with all
the safety rules applicable in the event of product failure.
Failure to take these precautions could result in death or serious
injury.
CAUTION
OVER-VOLTAGES
Exceeding the maximum recommended power supply threshold will
result in the product being destroyed.
• Check the motor's supply voltage before connecting it.
If these precautions are not taken, the result could be injury or
damage to equipment.
8.2.1. Voltage protection
The product has protection against over and under-voltages.
Protection against over-voltages:
The over-voltage threshold is set to 56V
(*)
.
When the power supply voltage exceeds the threshold, the product automatically goes into SAFE mode:
power to the motor is then cut and it is no longer controlled.
To reset the motor, it is necessary:
-
That the supply voltage is lower than 56V
(*)
-
The motor inputs are in OFF mode.
Protection against under-voltages:
When the power supply voltage drops below 9V, the product automatically switches to SAFE mode: power to
the motor is then cut and it is no longer controlled.
To reset the motor, it is necessary:
-
That the supply voltage is greater than 10V
-
The motor's On / Off input is in OFF mode.
(*)
36V prior to 15 October 2015
8.2.2. Temperature protection
The product includes temperature protection via a temperature sensor on the motor control board.
Temperature protection:
When the internal temperature exceeds 110°C, the product automatically switches to SAFE mode: power to
the motor is then cut and it is no longer controlled.
To reset the motor, it is necessary that:
-
The temperature is below 90°.
-
The motor's On / Off input is in OFF mode.
