YASKAWA GA800 Programming Manual page 619

*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 install a DC link choke, you must remove the jumper between terminals +1 and +2.
*3 Models 2110 to 2415 and 4060 to 4720 have a DC link choke.
*4 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].
*5 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.
*6 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.
*7 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.
*8 Cooling fan wiring is not necessary for self-cooling motors.
*9 The number of terminals is different for different models.
• R/L1, S/L2, T/L3, U/T1, V/T2, W/T3: There are 2 screws for each terminal on models 4477 - 4720.
• +3: Models 2169 - 2415 and 4208 - 4720 only. There are 2 screws for this terminal on models 4477 - 4720.
• +2: Models 2004 - 2082 and 4002 - 4044 only.
• +1, -: There are 2 screws for each terminal on models 2169, 2211, 4140, 4168, and 4477 - 4720.
• B1, B2: Models 2004 - 2138 and 4002 - 4168 only.
*10 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.
*11 Encoder circuit wiring (wiring to PG-B3 option) is not necessary for applications that do not use motor speed
feedback.
*12 Connect a 24 V power supply to terminals PS-AC to operate the control circuit while the main circuit power
supply is OFF.
*13 Install the jumpers between terminals SC-SP and SC-SN to set the MFDI power supply (sinking/sourcing mode
or internal/external power supply).
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 necessary between terminals SC-SN and terminals SC-SP.
*14 The maximum output current capacity for terminals +V and -V on the control circuit is 20 mA.
NOTICE: Do not install a jumper between terminals +V, -V, and AC. A closed circuit between these terminals will cause
damage to the drive.
*15 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).
*16 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.
*17 Do not ground the control circuit terminals AC or connect them to the drive.
