Verifying Installation Area of the Drive
Dimensions (W, H, D) and installation holes differ between A1000 and CR700.
CR700 has a larger depth. Ensure the sufficient space for installation. More depth is
required if using the installation attachment to match the same mounting holes used for
A1000.
Verifying the Installation Location of the Keypad (Digital Operator)
* Main device keypad (digital operator)
Keypad dimensions and the mounting position differ between A1000 and CR700.
If the control panel has been cut-out to accompany the previous drive, then either the
panel cut out dimensions or the drive installation position should be changed.
* Remote keypad (digital operator)
Previous remote keypads (the A1000 remote digital operator) are not compatible with
the newer models, so users will need to purchase a new keypad and to change the
panel cut-out dimension.
The keypad panel attachment (operator mounting bracket) for A1000 is not compatible
with CR700, so users will also need to purchase the new attachment.
Verifying Specialized Specifications
Check all specifications that may be unique to your drive, including the nameplate,
modifications and special coating. This information can be found on the original invoice
and product description.
Main
Circuit
Verifying Main Circuit Lines (Including Ground)
Location of the main circuit and its wiring configuration differ between A1000 and CR700.
If there is no room for the main circuit wiring, then rearrange the wiring, or use longer wires.
Verifying Main Circuit Terminal Specifications
CR700 (CR70A2003 to 2180 200V class 45kW or less, CR70A4002 to 4150 400V class
75kW or less) uses European terminals in the main circuit, so closed-loop crimp terminals
cannot be connected. Remove crimp terminals and prepare the wire ends.
Terminal shapes and sizes differ between A1000 and CR700.
Refer to Section 3-1 for terminal input/output specifications.
Control
Circuit
Verifying Control Circuit Lines
Location of the control circuit terminal block and its wiring configuration differ between
A1000 and CR700.
If there is no room for the control circuit wiring, then rearrange the wiring, or use longer wires.
Verifying Control Circuit Terminal Blocks and Specifications
CR700 uses European terminals in the control circuit, so closed-loop crimp terminals cannot
be connected. Remove crimp terminals and prepare the wire ends.
The number of terminals, terminal shapes, and terminal sizes differ between A1000 and
CR700.
Refer to Section 3-2 for terminal I/O specifications.

Software
Verifying Custom Software
Check if the software currently being used is Yaskawa’s software for crane. Contact
Yaskawa and confirm the software number if it is not clear whether the software is
standard or not.
Parameters
Verifying Parameter Settings
Parameters do not all match between A1000 and CR700.
After checking the parameters in the drive currently being used, follow the procedure in
Section 5 to set the appropriate parameters to match the new drive.
Contact Yaskawa if there are any parameters not covered in Section 5.
The support tool “Drive Wizard” for CR700 offers a Drive Replacement function for
converting parameter settings to CR700. (Available soon)
DriveWizard is not the same as DriveWizard Plus.
