ASG output and BSG output
ASG and BSG outputs are available in two types: transistor open-collector output (ASG1/GND, BSG1/GND) and line-
driver output (ASG2+/ASG2−, BSG2+/BSG2−). Use either type to suit the input system of the counter unit and other
functions of the controller.
The use of ASG and BSG outputs requires separate 5 VDC or 24 VDC power supply.
With the ASG output, pulses are output synchronously with and in proportion to the movement of the rack. The
output-pulse resolution will be the same as the motor resolution at the time power is supplied to the driver (as set by
the resolution select switches).
Counting ASG output pulses allows the lineard motor’s rack position to be monitored.
ASG output: Outputs pulse while the lineard motor operates.
BSG output: Detects the direction of lineard motor’s rack movement. It has a 90° phase difference with regard to ASG
output. The level of BSG output at the rise time of ASG output indicates the direction of lineard motor’s rack
movement.

•
Always connect either 5 VDC or 24 VDC as the power for ASG output and BSG output. Do not
connect 5 VDC and 24 VDC power supplies at the same time, as it may damage the driver and
power supplies.
•
The pulse output delays behind motor rotation by up to 1 ms. The output may be used to verify
the motor’s stop position.
Operating the electromagnetic brake
Operate the electromagnetic brake as follows:
1. ALARM output is in the OFF state immediately after the driver power is turned on. Check to see that ALARM
output has been reset (turned from OFF to ON), then turn on the electromagnetic brake.
2. Before inputting pulse signals to operate the motor, set the motor in the ready state by “releasing” the
electromagnetic brake.
3. To allow the electromagnetic brake to “hold” the load after the motor has completed its operation, turn the
electromagnetic brake off only after verifying that END (positioning complete) output has turned from OFF to ON.

To hold the load in position, apply the electromagnetic brake only after the lineard motor has
stopped. Do not use the brake to bring the moving lineard motor to a halt. Repeated braking for such
a purpose will wear the brake hub excessively, causing a decrease in its ability to hold.
