*
4: Be sure to protect non-Yaskawa braking resistors by thermal overload relay.
*
5: When using more than one braking unit connected in parallel, set one of
the braking units as the master, and set the others as slaves.
*
6: Connect fault relay output to multi-function digital input S (External Fault).
Connect the CDBR transistor short-circuit detection output to disconnect
main input power to the drive.
*
7: Connect directly to the drive terminal or install a terminal block.
*
8: Contact your Yaskawa or nearest sales representative for a replacement
manual when connecting braking units CDBR-
B
,
CDBR-
C, and
CDBR-
D in parallel.
*
1: Set L3-04
=
0 [Disabled] (default setting) when connecting the regenerative
converter, regenerative unit, braking unit and braking resistor unit. The
drive may not stop within the specifi ed deceleration time if L
3-04 is
changed to
1 through 5 [Enabled].
*
2: 200 V class drives do not require a control circuit transformer.
*
3: Set L8-55 to 0 to disable the protection function for the built-in braking
transistor when using a regenerative unit or another type of braking option in
lieu of the built-in braking transistor. If the protection function is enabled
under these conditions, it may cause a braking resistor fault (rF).
When connecting a separately-installed type braking resistor unit (model
CDBR) to drives with a built-in braking transistor (catalog codes CR
70
2003 to 2115, and CR70
4002 to 4150), connect the B1 terminal of the
drive to the positive terminal of the braking resistor unit and connect the
negative terminal of the drive to the negative terminal of the braking resistor
unit. The B
2 terminal is not used in this case.
