*1  This signal functions as the brake release input during normal operation, 

and as the ALARM-RESET input when the ALARM output is OFF.  

(Refer to "Resetting an ALARM" on page 6.)

*2  Releases the electromagnetic brake for the motor with electromagnetic 

brake.

*3  Not applicable to an induction motor which has four lead wires.

*4  For details, check "ALARM output" on page 6.

*5  Only for electromagnetic-brake motors.

Input/output„signals

The input/output circuits are initially set to sink logic. Switch the circuit mode 

between "sink logic" and "source logic" according to the external control 

equipment used. (Refer to "Switching between sink logic and source logic.")

„

z

Input„circuit„(internal„circuit)

The input-signal voltage is 24 VDC. 

Input signals are provided as photocoupler inputs.

The signal state indicates the "ON: current supplied" or "OFF: current not 

supplied" status of the internal photocoupler rather than the voltage level of 

the signal.

„

z

Output„circuit„(internal„circuit)

Output signals are provided as open-collector outputs.

The signal state indicates the "ON: current supplied" or "OFF: current not 

supplied" status of the internal transistor rather than the voltage level of the 

signal. 

Use a power source of 26.4 VDC or less, and limit the output current to  

10 mA or less.

Switching„between„sink„logic„and„source„logic

Use the sink/source selector switch on the side of the brake pack to switch the 

input/output circuit mode between "sink logic" and "source logic."

In an input circuit of sink logic, a signal turns ON when current flows out of 

the applicable input terminal.

In an input circuit of souce logic, a signal turns ON when current flows into 

the applicable input terminal.

The factory setting is sink logic. Set an appropriate mode after confirming the 

output circuit of the external control equipment to be used.

„

„

Connection„example

The connection example of page 4 is for sink logic. See page 5, for the 

connection example of source logic.

The direction of motor rotation indicates the direction as viewed from the 

output-shaft side. "CW" indicates clockwise and "CCW"counterclockwise.

The direction of gear-output shaft rotation may be opposite that of motor 

rotation, depending on the gear ratio of the gear head.
