Note 3 : Specification of the MCC (RELAY) confirmation contact
The C series amplifier makes the auxiliary contact (b-contact)
of the MCC, installed on the three-phase power line for motor
power, accessible to the outside. It is used to indicate when the
power to the motor is shut off. On the other hand, the SVU and
SVUC make the auxiliary contact of the dynamic brake circuit
relay (in the SVU1-130 and SVUC1-130, a-contact, and for
others, b-contact) accessible to the outside, in order to indicate
when the motor power is shut off.
Type Auxiliary
Contact
Terminal Signal Name
C series amplifier b contact T1 (7-8) MC1-MC2
SVU1-130, SVUC1-130 a contact T1 (7-8) RL1-RL2
Other SVU and SVUC b contact T1 (7-8) RL2-RL3
a contact : In dynamic brake, its contact is open.
b contact : In dynamic brake, its contact is short.
Note 4 : Conformance to TUV
Like the C series amplifier, the SVUC is not qualified for TUV
(because it has a built-in surge absorber for input protection).
When it is necessary to acquire qualification for CE marking,
use the SVU.
