Select the driver you will use according to the table below.
This board includes a Microcontroller-based driver monitoring system. It performs
enabling and monitoring functions for servo Drivers, and only enabling function for
stepper drivers. It is required connect the driver ERR/RES (servo drivers) or EN
(stepper driver) terminal to the pin 5 of each RJ45 driver connector.
Here is a brief description of how these functions are performed for each operation
mode.
Operation Mode 1 (G320/DG4S)
When the system starts, the C32 error/reset pins go to a low state (0V), making sure the
driver remains disabled. When SCHP and E-Stop function are checked and validated
and there is no fault signal coming from any driver, the system sends a high (5V) to the
driver’s error/reset pins for about 5 seconds to enable the drivers. After that the system
monitors the driver’s err/res pins. If a fault occurs on any driver (0V in driver ERR/RES
pin) or an external fault occurs (E-Stop or SCHP fault), the system stops and sends an
e-stop signal (Active low) to the controller. All outputs on the board are disabled and
the drivers will be disabled by sending a LOW (0V) to the drivers ERR/RES pin. The
system will remain that way until the conditions to restart are present again.
Operation Mode 2 (G203)
When the system starts, the C32 enable pins go to a HIGH state (5V). When SCHP
and E-Stop function are checked and validated, the system send a LOW (0V) to the
driver’s EN pin for about 2 Sec, enabling the drivers. If an external error occurs, the
system stops, resets the CNC software and sends a HIGH (5V) to the drivers EN pin.
The system will remain that way until the conditions to restart are present again.
Operation Mode 3 (G210/201)
When the system starts, the C32 enable pins go to a LOW state (0V). When SCHP and
E-Stop function are checked and validated, the system send a HIGH (5V) to the Drivers
EN pin for about 2 Sec, enabling the Drivers. If an external error occurs, the system
stops, resets the CNC software and sends a LOW (0V) to the drivers EN pin. The
system will remain that way until the conditions to restart are present again.
