Drive Control & Communication
NOTE 5 - AC Tech Register #101, Parameter 51 - Software Version
When parameter #101 is read, the number of registers can be either 1 or 4. In case of 4
register read, the drive will send 8 bytes of data back to the MASTER. It does not mean
the read function reads parameter #101, #102, #103, and #104. This is a special case to
handle the ASCII string representing software version. The ASCII string may look like this:
“ TF12801”. In case of reading one register, received high byte contains software version
and low byte revision number. If received word contains hexadecimal number 0x8001 it
translates to:
0x80 --> decimal 128 (software version) and
0x01 --> decimal 1 (revision number).
NOTE 6 - AC Tech Registers 107 & 108 - Digital I/O
Table 18 lists the format of AC Tech Register #107, Parameter 57 - TB Strip Status.
Table 19 lists the format of AC Tech Register #108, Parameter 58 - Keypad Status.

NOTE - AC Tech Registers #134 & 142
Register #134, Parameter 84 (Stator Resistance) and Register #142, Parameter 92 (Motor
