Grounding protection #
The grounding device is set below the junction box of the CNC press brake. In order to ensure the safety of personnel and equipment, the grounding of the CNC press brake should be reliably connected with the workshop grounding grid.
Emergency stop #
In order to facilitate users to use the CNC press brake safely and reliably, three emergency stop buttons SB1, SB2 and Sb3 are set, which are installed on the control cabinet door, the hanging box of the NC system and the mobile operation station respectively.
If the CNC press brake fails or is abnormal, press one of the three buttons arbitrarily, and the CNC press brake will stop running immediately
Overload (phase failure) protection of motor #
In order to overload (or open phase) the above motors for a long time, all motors of the CNC press brake adopt thermal relays as protection parts.
In case of fault, the power supply of the motor can be cut off automatically, so as to achieve the purpose of protecting the motor.
