Verifying Option Cards
Option cards for A1000 are compatible with CR700.
Note that the following option software versions and later versions with larger software
numbers are compatible with CR700.
- DeviceNet
SI-N3 => PRG: 1114
- MECHATROLINK-II
SI-T3 => PRG: 6108
- MECHATROLINK-III
SI-ET3 => PRG: 6202
Peripherals
Braking Resistor
Check if the drive currently being used has a braking resistor.
If there is a braking resistor (ERF type) installed to the backside of the drive,
then note the following:
(1) The braking resistor installation attachment used for A1000 is not compatible with
CR700. Although the overall dimensions are the same, CR700 requires a special
attachment.
(Refer to Section 4-4 for how to order the attachment and for its installation
dimensions.)
Standard vibration tolerance specifications may not be guaranteed if an installation
attachment is used. Yaskawa recommends installing the braking resistor in a
separate location if the drive is used in an area with a high degree of vibration.
(2) If planning to use the same ERF-type braking resistor installed to A1000 in the new
CR700 drive and the cable is too short, replace the cable with a longer one only if the
wire specifications are the same. Ensure that the cable extension is properly
insulated.
Braking Units
The braking unit can be transferred to CR700 as-is without making any changes.
If using a braking unit with catalog code CR70A2115 or below (200 V class), or catalog
code CR70A4150 or below (400 V class), then set L8-55 = 0 [Internal Braking Transistor
Protection = Disabled].
Note: If using a drive with a built-in braking transistor (catalog code CR70A2115 or below
for 200 V class drives, or catalog code CR70A4150 or below for 400 V class
drives), then connect the drive terminal B1 to the positive terminal of the braking
unit, and connect the negative terminal of the drive and the negative terminal of the
braking unit. Terminal B2 is not used in CR700.
AC or DC Reactor
The AC or DC reactor can be transferred to CR700 as-is without making any changes.
Noise Filter
The noise filter can be transferred to CR700 as-is without making any changes.
Fuse
The fuses can be transferred to CR700 as-is without making any changes.
- Refer to the instruction manual included with the product for replacing the drive.
