When using the amplifier with VCM,
connect the U and W terminals
Note1) To attach a dynamic brake resistor externally, set switch XS to "2" side.
Note2) Make the electromagnetic contactor (MC2) the same as the electromagnetic contactor (MC1) of the main circuit.
Note 3) When auxiliary contact is provided and main contact is welded Configure protection
so that servo on will not be turned on by external sequence
Note 4) Please use three 1.2 Ω 400 W dynamic brake resistors.
Please attach dynamic brake resistance to incombustible material such as metal.
Note 5) Install the thermal protector on the dynamic brake resistor and monitor with the upper side I / O and
configure the protection so that the servo will not be turned on in the sequence during thermal protector operation.
Note 6) If the thermal protector can not be monitored by the upper I / O, input the thermal protector output
between L2C and DB2 so that the dynamic brake does not operate when temperature protection works.
* External dynamic brake resistance should be used when exceeding the dynamic brake resistance capability.
* Do not use the built-in dynamic brake and the external dynamic brake together.
* For details, refer to 7-1 Power connector XA, XB, XC, XD and terminal block.
