TOEPC7106170YB YASKAWA AC Drive GA500 Installation & Primary Operation
*1
Set the wiring sequence to de-energize the drive with the MFDO. 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 ter1 and +2.
*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, and +2. Do not connect an AC power supply lines 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 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.
*10
WARNING
Electrical Shock Hazard. Do not ground the shield of the control wiring to
the protective ground terminal. It does not comply with technical standards and local codes and
can cause serious injury or death.
*11
The maximum output current capacity for teV on the control circuit is 20 mA.
NOTICE
Damage to Equipment. Do not install a jumper between terV and
AC. A closed circuit between these terminals will cause damage to the drive.
*12
DIP switch S1 sets terminal A2 for voltage or current input. The default setting for S1 is current input (
“
I
”
side).
