YASKAWA TOEPYAIGA8001B GA800 Drive Maintenance & Troubleshooting 345
*1 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] .
*2 When you use a braking unit, set L8-55 = 0 [Internal DB TransistorProtection = Disable] . If L8-55 = 1 [Protection Enabled] , the drive
will detect rF [Braking Resistor Fault] .
*3 When you use a braking 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.
*4 When you connect a braking unit (CDBR series) to drive models T140 and T168, 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.
*5 Cooling fan wiring is not necessary for self-cooling motors.
*6 The number of terminals is different for different models.
•
Terminals U/T1, V/T2, W/T3: There are 2 screws for each terminal on models T477 to T720.
•
Ter3 and -: There are 2 screws for this terminal on models T477 to T720.
*7 Connect peripheral options to terminals - and +3.
WARNING! Fire Hazard. Only connect factory-recommended devices or circuits to drive terminals - and +3. Do not connect
AC power supply lines to these terminals. Incorrect wiring can cause damage to the drive and serious injury or death from fire.
*8 Encoder circuit wiring (wiring to PG-B3 option) is not necessary for applications that do not use motor speed feedback.
*9 Connect a 24 V power supply to terminals PS-AC to operate the control circuit while the main circuit power supply is OFF.
*10 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.
NOTICE: Damage to Equipment. Do not close the circuit between terminals SP-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.
• 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.
*11 The maximum output current capacity for terV and -V on the control circuit is 20 mA.
NOTICE: Do not install a jumper between terV, -V, and AC. A closed circuit between these terminals will cause
damage to the drive.
*12 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).
*13 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.
*14 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.
*15 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.
*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 switch S5 sets terminal FM and AM for voltage or current output. The default setting for S5 is voltage output ( “ V ” side).
*18 Set DIP switch S2 to “ ON ” to enable the termination resistor in the last drive in a MEMOBUS/Modbus network.
*19 Use only SOURCE Mode for Safe Disable input.
*20 Disconnect the jumper between H1 and HC and H2 and HC to use the Safe Disable input.
