Standard Drive Connection Diagram

Set the wiring sequence so the fault relay output de-energizes the drive. If the drive outputs a fault during fault restart when you use the fault restart function, set L5-02 = 1 [Fault Contact at Restart Select = Always Active] to de-energize the drive. Be careful when you use a cut-off sequence. The default setting for L5-02 is 0 [Active Only when Not Restarting].

When you install a DC reactor, you must remove the jumper between terminals +1 and +2. Ground the DC reactor (option) on the back of the mounting base. Remove all paint from the mounting surface of the control panel.

Models 2110 to 2415 and 4060 to 4H12 have a DC reactor.

When you use a regenerative converter, regenerative unit, or braking unit, set L8-55 = 0 [Internal DB TransistorProtection = Disable]. If L8-55 = 1 [Protection Enabled], the drive will detect rF [Braking Resistor Fault].

When you use a regenerative converter, regenerative unit, braking 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.

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 fault relay output.

When you connect a braking unit (CDBR series) or a braking resistor unit (LKEB series) to drive models 2110, 2138, and 4103, make sure that you use wires that are in the range of the applicable gauges for the drive. A junction terminal is necessary to connect wires that are less than the applicable gauge to the drive. Contact Yaskawa or your nearest sales representative for more information about selection and installation of the junction terminal.

Cooling fan wiring is not necessary for self-cooling motors.

The number of terminals is different for different models.

• Terminals R/L1, S/L2, T/L3, U/T1, V/T2, W/T3: There are two screws for each terminal block on models 4453 to 4675. There are four screws for each terminal block on models 4810 to 4H12.

• Terminal +3: Models 2169 to 2415 and 4208 to 4H12 only. There are two screws for each terminal block on models 4453 to 4675. There are four screws for each terminal block on models 4810 to 4H12.

• Terminal +2: Models 2004 to 2082 and 4002 to 4044 only.

• Terminals +1, -: There are two screws for each terminal block on models 2169, 2211, 4140, 4168, and 4453 to 4675. There are four screws for each terminal block on models 4810 to 4H12.

• Terminal B1: Models 2004 to 2138 and 4002 to 4168 only.

Connect peripheral options to terminals -, +1, +2, B1, and B2.

Encoder circuit wiring (wiring to PG-B3 option) is not necessary for applications that do not use motor speed feedback.

Connect a 24 V power supply to terminals PS-AC to operate the control circuit while the main circuit power supply is OFF.

To set the MFDI power supply (Sinking/Sourcing Mode or internal/external power supply), install or remove a jumper between terminals SC-SP or SC-SN depending on the application.

• Sinking Mode, Internal power supply: Install the jumper to close the circuit between terminals SC-SP.

  Notice
  	Damage to Equipment Do not close the circuit between terminals SC-SN. If you close the circuits between terminals SC-SP and terminals SC-SN at the same time, it will cause damage to the drive.

• Sourcing Mode, Internal power supply: Install the jumper to close the circuit between terminals SC-SN.

  Notice
  	Damage to Equipment Do not close the circuit between terminals SC-SP. If you close the circuits between terminals SC-SP and terminals SC-SN at the same time, it will cause damage to the drive.

• External power supply: Remove the jumper from the MFDI terminals. It is not necessary to close the circuit between terminals SC-SP and terminals SC-SN.

The maximum output current capacity for terminals +V and -V on the control circuit is 20 mA.

DIP switches S1-1 to S1-3 set terminals A1 to A3 for voltage or current input. The default setting for S1-1 and S1-3 is voltage input (“V” side). The default setting for S1-2 is current input (“I” side).

DIP switch S4 sets terminal A3 for analog or PTC input. Set DIP switch S1-3 to the “V” side, and set H3-05 = 0 [Terminal A3 Signal Level Select = 0 to 10V (Lower Limit at 0)] to set terminal A3 for PTC input with DIP switch S4.

Do not ground control circuit terminal AC or connect it to the drive chassis.

Connect the positive lead from an external 24 Vdc power supply to terminal PS and the negative lead to terminal AC.

Use multi-function analog monitor outputs with analog frequency meters, ammeters, voltmeters, and wattmeters. Do not use monitor outputs with feedback-type signal devices.

Jumper switch S5 sets terminals FM and AM for voltage or current output. The default setting for S5 is voltage output (“V” side).

Set DIP switch S2 to “ON” to enable the termination resistor in the last drive in a MEMOBUS/Modbus network.

Use only Sourcing Mode for Safe Disable input.

Disconnect the wire jumpers between H1 and HC and H2 and HC to use the Safe Disable input.

Set the wiring sequence to de-energize the drive with the fault relay output. If the drive outputs a fault during fault restart when you use the fault restart function, set L5-02 = 1 [Fault Contact at Restart Select = Always Active] to de-energize the drive. Be careful when you use a cut-off sequence. The default setting for L5-02 is 0 [Active Only when Not Restarting].
