<1> Set up a thermal relay sequence to disconnect drive main power in the event of an overheat condition on the dynamic braking option.

<2> Set L8-55 to 0 to disable the protection function of the built-in braking transistor of the drive when using an optional regenerative converter or dynamic braking option. Leaving L8-55 enabled may cause a braking resistor fault (rF). Additionally, disable Stall Prevention (L3-04 = 0) when using an optional regenerative converter, regenerative or braking units, or dynamic braking option. Leaving If L3-04 enabled may prevent the drive from stopping within the specified deceleration time.

<3> Supplying power to the control circuit separately from the main circuit requires 24 V power supply (option).

<4> This figure illustrates an example of a sequence input to S1 through S8 using a non-powered relay or an NPN transistor. Install the wire link between terminals SC-SP for Sink mode, between SC-SN for Source mode, or leave the link out for external power supply. Never short terminals SP and SN, as it will damage the drive.

<5> This voltage source supplies a maximum current of 150 mA when not using a digital input card DI-A3.

<6> The maximum output current capacity for the +V and -V terminals on the control circuit is 20 mA. Never short terminals +V, -V, and AC, as it can cause erroneous operation or damage the drive.

<7> Slide switch S6 selects N.C. or N.O. as the state of the DM+ and DMterminals for EDM output. Slide switch S6 is available on terminal board ETC74030o.

<8> Set DIP switch S1 to select between a voltage or current input signal to terminal A2. The default setting is for current input.

<9> Set DIP switch S4 to select between analog or PTC input for terminal A3.

<10> Set DIP switch S2 to the ON position to enable the termination resistor in the last drive in a MEMOBUS/Modbus network. <11> Use jumper S3 to select between Sink mode, Source mode, and external power supply for the Safe Disable inputs. <12> Disconnect the wire jumper between H1 - HC and H2 - HC when utilizing the Safe Disable input.

<13> Monitor outputs work with devices such as analog frequency meters, ammeters, voltmeters, and wattmeters. They are not intended for use as a feedback-type signal.

<14> Use jumper S5 to select between voltage or current output signals at terminals AM and FM. Set parameters H4-07 and H4-08 accordingly.

<15> Self-cooling motors do not require the same wiring necessary for motors with cooling fans.

<16> Refer to local codes for proper branch circuit protection (BCP) on the primary side of the 6-Phase/12-Pulse transformer. <17> Fuse selection for the secondary side is of the 6-Phase/12-Pulse transformer is shown in Table 13 and Table 14.

WARNING! Sudden Movement Hazard. Do not close the wiring for the control circuit unless the multifunction input terminal parameters are properly set. Improper sequencing of run/stop circuitry could result in death or serious injury from moving equipment.

WARNING! Sudden Movement Hazard. Ensure start/stop and safety circuits are wired properly and in the correct state before energizing the drive. Failure to comply could result in death or serious injury from moving equipment. When programmed for 3-Wire control, a momentary closure on terminal S1 may cause the drive to start.

WARNING! Sudden Movement Hazard. When using a 3-Wire sequence, set the drive to 3-Wire sequence prior to wiring the control terminals and set parameter b1-17 to 0 so the drive will not accept a Run command at power up (default). If the drive is wired for a 3-Wire sequence but set up for a 2-Wire sequence (default), and parameter b1-17 is set to 1 so the drive accepts a Run command at power up, the motor will rotate in reverse direction at drive power up and may cause injury.

WARNING! Sudden Movement Hazard. Confirm the drive I/O signals and external sequence before executing the application preset function. Executing the application preset function or setting A1-06 ≠ 0 will change the drive I/O terminal functions and may cause unexpected equipment operation. Failure to comply may cause death or serious injury.

NOTICE: When using the automatic fault restart function with wiring designed to shut off the power supply upon drive fault, make sure the drive does not trigger a fault output during fault restart (L5-02 = 0, default). Failure to comply will prevent the automatic fault restart function from working properly.

Installing a Transformer

Install a 6-Phase/12-Pulse isolation transformer with output windings phase-shifted by 30 electrical degrees or install a Hybrid 6-Phase topology on the power supply.

Installing a 3-Phase Line Monitor

Yaskawa requires installation of a 3-Phase line monitor to protect the drive in the event of an input line phase loss.

The 3-Phase line monitor must be installed on the primary circuit of the 6-Phase/12-Pulse transformer and connected to the drive to remove the Run command when a phase loss condition occurs.

The drive power circuit may be damaged during a phase-loss condition if a 3-Phase line monitor is not properly installed. Contact a Yaskawa representative for help selecting the optimum 3-Phase line monitor and fuses.

u Main Circuit Wiring

This section describes the functions, specifications, and procedures required to safely and properly wire the main circuit in the drive.

NOTICE: Do not solder the ends of wire connections to the drive. Soldered wiring connections can loosen over time. Improper wiring practices could result in drive malfunction due to loose terminal connections.

NOTICE: Do not switch the drive input to start or stop the motor. Frequently switching the drive on and off shortens the life of the DC bus charge circuit and the DC bus capacitors, and can cause premature drive failures. For the full performance life, refrain from switching the drive on and off more than once every 30 minutes.

u Wire Gauges and Tightening Torques

Use the tables in this section to select the appropriate wires and crimp terminals. Gauges listed in the tables are for use in the United States.

Note:	1. Wire gauge recommendations based on drive continuous current ratings (ND) using 75 °C 600 Vac vinyl-sheathed wire assuming ambient
	temperature within 40 °C and wiring distance shorter than 100 m.

2.Terminals 3 and are for connecting optional power devices. Use caution to connect only approved devices to the correct terminal(s).

•Consider the amount of voltage drop when selecting wire gauges. Increase the wire gauge when the voltage drop is greater than 2% of motor rated voltage. Ensure the wire gauge is suitable for the terminal block. Use the following formula to calculate the amount of voltage drop:

Line drop voltage (V) = 3 × wire resistance (Ω/km) × wire length (m) × current (A) × 10-3

•Refer to CDBR manual TOBP C720600 00/TOBP C720600 01 for dynamic braking wire gauges.

•Use terminals 3 and when connecting a CDBR dynamic braking unit.

•Do not connect a regenerative converter or a regenerative unit to the 6-Phase/12-Pulse drive.

•Refer to UL Standards on page 84 for information on UL compliance.

Yaskawa recommends using closed-loop crimp terminals on all drive models. UL/cUL approval requires the use of closedloop crimp terminals when wiring the drive main circuit terminals. Use only the tools recommended by the terminal manufacturer for crimping. Refer to Closed-Loop Crimp Terminal Size on page 86 for closed-loop crimp terminal recommendations.

The wire gauges listed in Table 5 are Yaskawa recommendations and are based on the 6-Phase input current ratings specified in Table 14. Refer to local codes for proper wire gauge selections.
