These drives have the following connectors:
F. H3/10 9
ACD|SCD 2.35|2.50 and SCD 2.75 compact drives. Connectors.
1. Power connector for motor (U, V, W) and mains connection (R, S, T).
Note
. RST has been the classic nomenclature for mains phases. L1L2L3 is its equivalent nowadays.
2. Connector for the external Ballast resistor (Re) and for accessing the power bus (L+, L-).
3. External Ballast resistor.
X1. Connector for the internal 24 V DC power supply (2-ph. with line voltage V AC).
X2. Connector for the basic control signals.
X3. Connector with two possible uses:
• as output of the encoder simulator.
• as input of the direct feedback for the position loop.
X4. Connector for motor feedback connection (encoder).
X5. Connector for RS-232 serial line connection.
X6. SERCOS-II or CAN interface connector.
X7. Connector for external acknowledgment of the status of the safety relay.
SL1. Slot for the cards A1, 16DI-8DO and 8DI-16DO.
SL2. Slot for the cards 16DI-8DO and 8DI-16DO.
