Signature Label
The Signature Label on the heat sink indicates capacity in wattage for each Motor Driver
module.
Model Capacity (W)
CACR-A5-SU3C 50 W
CACR-01-SU3C 100 W
CACR-02-SU3CY1 200 W
CACR-04-SU3C 400 W
CACR-08-SU3C 750 W
The power rating (wattage) of the mounted Motor Driver module corresponds to the
wattage of its driving motor. However, a 150W motor requires either a 100W or 200W
Motor Drive module depending on the Manipulator models. For details, refer to the
maintenance parts list in the Manipulator manual.
CT data
The CT data beside the signature label indicates specific information to each Motor
Driver module. In order to optimize the Controller’s control over the Manipulator, the
exact same values as indicated here must be set up in the Controller after the motor Driver
module is replaced.
There are two kinds of CT data as follows:
4B-**** : “CT OFFSET”.
4D-**** : “CTGAIN”.
The mark, “*”, on the CT data is indicated with “0” to “9” and “A” to “F”.
The indication is different depending on the Driver module.
Record the CT data to be entered in the Controller before placing the Top Cover back on
the Controller when replacing the Motor Driver module. After the replacement, refer to
User’s Guide and set up the CT data.
