3.2 Electrical Installation
*3 When you use a regenerative converter or regenerative unit, set L8-55 = 0 [Internal DB TransistorProtection = Disable]. If L8-55 =
1 [Protection Enabled], the drive will detect rF [Braking Resistor Fault].
*4 When you use a regenerative converter, regenerative unit, braking resistor, or braking resistor unit, set L3-04 = 0 [Stall Prevention
during Decel = Disabled]. If L3-04 = 1 [General Purpose], the drive could possibly not stop in the specified deceleration time.
*5 When you use an ERF-type braking resistor, set L8-01 = 1 [3% ERF DB Resistor Protection = Enabled] and set a wiring sequence to
de-energize the drive with the MFDO.
*6 Cooling fan wiring is not necessary for self-cooling motors.
*7 Connect peripheral options to terminals -, +1, +2, B1, and B2.
WARNING! Fire Hazard. Only connect factory-recommended devices or circuits to drive terminals B1, B2, -, +1, +2, and
+3 terminals. Do not connect AC power to these terminals. Incorrect wiring can cause damage to the drive and serious
injury or death from fire.
*8 Connect a 24 V power supply to terminals PS-AC to operate the control circuit while the main circuit power supply is OFF.
*9 To set the MFDI power supply (Sinking/Sourcing Mode or internal/external power supply), install wire jumpers between terminals
SC-SP and SC-SN.
NOTICE: Do not close the circuit between terminals SP and SN. A closed circuit between these terminals will cause
damage to the drive.
• Sinking Mode: Install a jumper between terminals SC and SP.
NOTICE: Do not close the circuit between terminals SC and SN. A closed circuit between these terminals will cause
damage to the drive.
• Sourcing Mode: Install a jumper between terminals SC and SN.
NOTICE: Do not close the circuit between terminals SC and SP. A closed circuit between these terminals will cause
damage to the drive.
• External Power Supply: No jumper is necessary between terminals SC-SN and terminals SC-SP.
*10 The maximum output current capacity for terminal +V on the control circuit is 20 mA.
NOTICE: Damage to Equipment. Do not install a jumper between terminals +V and AC. A closed circuit between these
terminals will cause damage to the drive.
*11 DIP switch S1 sets terminal A2 for voltage or current input. The default setting for S1 is current input ("I" side).
*12 Do not ground the control circuit terminals AC or connect them to the drive.
NOTICE: Do not ground the AC control circuit terminals and only connect the AC terminals according to the product
instructions. If you connect the AC terminals incorrectly, it can cause damage to the drive.
*13 Connect the positive lead from an external 24 Vdc power supply to terminal PS and the negative lead to terminal AC.
NOTICE: Connect terminals PS and AC correctly for the 24 V power supply. If you connect the wires to the incorrect
terminals, it will cause damage to the drive.
*14 Set DIP switch S2 to "ON" to enable the termination resistor in the last drive in a MEMOBUS/Modbus network.
*15 Use only Sourcing Mode for Safe Disable input.
*16 Use multi-function analog monitor outputs with analog frequency meters, ammeters, voltmeters, and wattmeters. Do not use monitor
outputs with feedback-type signal devices.
*17 Jumper S5 sets terminal AM for voltage or current output. The default setting for S5 is voltage output ("V" side).
*18 Disconnect the wire jumpers between H1 and HC and H2 and HC to use the Safe Disable input.
