:
We recommend that the sequence that de
-
energizes the power supply
be set via the fault relay output for the drive.
2
:
Be sure to remove the jumper between terminals
+
1
and
+
2
when
installing a DC reactor
(
option
)
.
3
:
Catalog codes CH70A2088 to 2415 and 4045 to 4605 have a built
-
in DC
reactor.
4
:
Be sure to set L
8
-
55
=
0
[
Internal DB Transistor Protection = Disable
]
when using an optional regenerative converter, regenerative unit, or
braking unit. Leaving L
8
-
55
=
1
[
Protection Enabled
]
can cause rF
[
Braking Resistor Fault
]
.
5
:
Set L
3
-
04
=
0
[
Disabled
] (
default setting
)
when connecting the
regenerative converter, regenerative unit, braking unit and braking
resistor unit. The drive may not stop within the specified deceleration
time if L
3
-
04
is changed to
1
through
5
[
Enabled
]
.
6
:
Set L
8
-
01
=
1
[
3
% ERF DB Resistor Protection = Enabled
]
and set a
sequence to de
-
energize the drive with the fault relay output when using
an ERF
-
type braking resistor.
7
:
When connecting a braking unit
(
CDBR series
)
or a braking resistor unit
(
LKEB series
)
to the catalog code CH70A2088, 2115, and 4091, use wires
that are in the range of the applicable gauges for the drive. A junction
terminal is required when connecting wires that are less than the
applicable gauge to the drive. Contact Yaskawa or your nearest sales
representative for details on selection and installation of the junction
terminal.
8
:
Terminals -,
+
1
,
+
2
, B
1
and B
2
are the optional connection terminals. Do
not connect an AC power supply to terminals -,
+
1
,
+
2
, B
1
, and B
2
.
Failure to obey can cause damage to the drive and peripheral devices.
9
:
Use a sequence that shuts the power OFF by Fault relay output.
10
:
Self
-
cooling motors do not require the wiring for the motors with cooling
fans.
11
:
Connect a
24
V power supply to terminals PS
-
AC to operate the control
circuit while the main circuit power supply is OFF.
12
:
Check that the wiring is set up so that the motor rotates in forward
(
FOR
)
when hoisting, and reverse
(
REV
)
when lowering in every control
method.
13
:
The baseblock is released when the external baseblock command is
ON.
14
:
Use a wire jumper between terminals SC and SP or SC and SN to set
the MFDI power supply to SINK Mode, SOURCE Mode, or External
power supply. Do not short circuit terminals SP and SN. Failure to obey
will cause damage to the drive.
・
SINK Mode
:
Install a jumper between terminals SC and SP.
Do not short circuit terminals SC and SN. Failure to obey
will cause damage to the drive.
・
SOURCE Mode
:
Install a jumper between terminals SC and SN.
Do not short circuit terminals SC and SP. Failure to
obey will cause damage to the drive.
・
External power supply
:
No jumper necessary between terminals SC
and SN or terminals SC and SP.
15
:
The output current capacity of the +V and
-
V terminals on the control
circuit is
20
mA. Do not install a jumper between terminals +V,
-
V, and
AC. Failure to obey can cause damage to the drive.
16
:
DIP switch S
1
set terminal A
2
for voltage or current input. The default
setting for S
1
is current input
(
“
I
”
side
)
.
17
:
DIP switch S
4
sets terminal A
3
for analog or PTC input.
18
:
Connect the positive lead from an external
24
Vdc power supply to
terminal PS and the negative lead to terminal AC. Reversing polarity can
cause damage to the drive.
19
:
Use multi
-
function analog monitor outputs with analog frequency
meters, ammeters, voltmeters, and wattmeters. Do not use monitor
outputs with feedback
-
type signal devices.
20
:
Set DIP switch S
2
to
“
ON
”
to enable the termination resistor in the last
drive in a MEMOBUS/Modbus
(
RTU mode
)
network.
21
:
Use sourcing mode when using an internal power supply for Safe
Disable input.
22
:
Disconnect the wire jumper between H
1
and HC, and H
2
and HC to use
the Safe Disable input.
