Notes:
1: Only 240V 0.5-25HP and 480V 1-30HP have a built-in braking transistor. The braking resistor can be connected
directly between P and BR or B1/P and B2. Others require braking unit and resistor. See section 3.17 for details.
2: Functional Safety input SF and SG should be a normally closed input. This input should be closed to enable the
AC Drive output. A jumper is placed between SF and SG from the factory.
3: Use jumper JP1 to select between Sink (NPN, with –24V common, factory default) or Source (PNP, with +24V
common) for multi-function digital input terminals S1–S6.
4: Use jumper JP2 to switch between voltage and current input for Multi-function analog input 1 (AI1).
5: Use jumper JP3 to switch between voltage and current input for Multi-function analog input 2 (AI2).
6: Grounding impedance: 240V class - less than 100Ω; 480V class - less than 10Ω.
Greater impedance indicates a poor ground.
