*3
Models 2110 to 2415 and 4060 to 4675 have a DC reactor.
*4
When you use an optional regenerative converter, regenerative unit, or braking unit, set
L8-55 = 0 [Internal
DB TransistorProtection = Disable]
to disable the protection function of the drive braking transistor. 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
Connect peripheral options to terminals -, +1, +2, B1, and B2.
WARNING!
Electrical Shock Hazard. Use terminals -, +1, +2, B1, and B2 to connect options to the drive. Do not connect
an AC power supply lines to these terminals. Failure to obey can cause death or serious injury.
*10 Encoder circuit wiring (wiring to PG-B3 option card) is not necessary for applications that do not use motor
speed feedback.
*11 Connect 24 V power to terminal PS-AC while the power to the drive control circuit is ON and only the main
circuit is OFF.
*12 Install a wire jumper between terminals SC-SP-SN to select the type of the power supply for MFDI (sinking/
sourcing mode or internal/external power supply).
NOTICE:
Do not close the circuit between terminals SP and SN. Failure to obey 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. Failure to obey 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. Failure to obey will cause damage to the drive.
•
External power supply: Remove the wire jumper between terminals SC-SN and terminals SC-SP.
*13 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. Failure to obey can cause damage to the drive.
*14 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).
*15 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.
*16 Do not ground the control circuit terminals AC or connect them to the drive.
WARNING!
Do not connect the AC control circuit terminals to ground. Failure to obey can cause drive malfunction or
failure.
*17 Connect the positive lead from an external 24 Vdc power supply to terminal PS and the negative lead to
terminal AC.
NOTICE:
Do not connect terminals PS and AC inversely. Failure to obey will cause damage to the drive.
*18 Use multi-function analog monitor outputs with analog frequency meters, ammeters, voltmeters, and
wattmeters. Do not use monitor outputs with feedback-type signal devices.
*19 Jumper switch S5 sets terminal FM and AM for voltage or current output. The default setting for S5 is
voltage output (
“
V
”
side).
*20 Set DIP switch S2 to
“
ON
”
to enable the termination resistor in the last drive in a MEMOBUS/Modbus
network.
*21 Use only SOURCE Mode for Safe Disable input.
*22 Disconnect the wire jumper between H1 and HC, and H2 and HC to use the Safe Disable input.
