6-4-2 Manually releasing the magnetic brakes
The intelligent servomotor has a relay for controlling the brakes in the amplifier, so the brakes cannot
be released even if power is supplied to the 24V power terminal (BR, RG) for the cannon plug brakes.
Release the brakes with the following method when the brakes need to be released for handling when
assembling, adjusting or servicing the machine.
(1) Method 1
Remove the amplifier section and input the 24V power to the motor brakes. There is no polarity.
Refer to section "9-3. Replacing the unit" for details on removing and installing the amplifier
section.
The amplifier terminal is a connector, so prepare the following connector beforehand.
Plug housing
: SMP-02V-BC
Socket contact : BHF-001T-0.8BS (J.S.T. Mfg Co., Ltd.)
(2) Method 2
Enter the brake release mode by changing the MON signal, normally used for the axis No.
selection, several times.
1) Prepare the circuit operation box shown with the dotted line below, and connect with the
intelligent servomotor as shown in the drawing.
2) Open SW1 and SW2.
3) Input 200VAC to the LL1 and LL2 terminals.
→
The LED will turn ON.
4) Turn SW1 ON.
→
The LED will flicker.
5) Turn SW2 ON.
→
The LED will turn OFF.
6) Turn SW2 OFF.
→
The LED will turn ON, and the relay in the
amplifier will turn ON.
7) Input 24VDC to the BR and RG terminals.
→
The brakes will be released.
8) Thereafter, when SW2 is turned ON the brakes will be applied, and when turned OFF, the
brakes will be released.
