Oriental motor BLH Series - Output Signals

I/O signals

TL input
The TL input is a signal to switch whether to enable or disable the torque limiting function.
When the TL input is turned ON, the torque limiting function is enabled.
The maximum value of the motor output torque is limited based on the set torque limiting value.
When the TL input is turned OFF, the torque limiting function is disabled, and the maximum value of the motor output
torque will be the peak torque (200%).
Note
•
The TL input is always ON (active state) as an internal signal if it is not assigned to the direct input or remote input.
When this signal is in an ON state (active state), the torque limiting function is enabled (the TL input is not assigned
at the time of shipment).
•
If the TL input is assigned to both the direct input and the remote input or to multiple terminals, when all assigned
input terminals are turned ON, it is in an ON state (active state) as an internal signal.

EXT-ERROR input
The EXT-ERROR input is a signal for emergency stop.
When this signal is turned OFF, an alarm is generated to stop the motor instantaneously.
Note
•
The EXT-ERROR input is always ON (active state) as an internal signal if it is not assigned to the direct input. When
this signal is in an ON state (active state), the external stop alarm is not generated (the EXT-ERROR input is not
assigned at the time of shipment).
•
If the EXT-ERROR input is assigned to multiple direct input terminals, when all assigned input terminals are turned
ON, it is in an ON state (active state) as an internal signal.
•
The EXT-ERROR input cannot be assigned to the remote input.

SPEED-OUT output
30 pulses are output while the motor output shaft makes one revolution in synchronization with the motor rotation.
The pulse width of output pulse signals is 0.2 ms. The motor rotation speed can be calculated using the SPEED-OUT
output.

Note
•
Changing the logic level setting is not available for the SPEED-OUT output.
•
The SPEED-OUT output cannot be assigned to the remote output.
•
The SPEED-OUT output repeats a state of ON or OFF. The SPEED-OUT output may be in a state of OFF depending
on the acquisition timing by the
MEXE02
or RS-485 communication even if the SPEED-OUT output (ON-OFF) is
activated.

ALM-A output, ALM-B output
This is a signal to output the status of alarm generation. If an alarm is generated, the ALM-A output is turned ON (in the
case of normally open), and the ALM-B output is turned OFF (in the case of normally closed).
