Drive Control & Communication
5.4.8 Commanded Rotational Direction - Registers #24 & 29
Table 17 lists the Commanded Rotational Direction (Register #24 byte D6L or Register #29 DL)
Table 17: Commanded Rotational Direction

0 FORWARD
1 REVERSE
5.5 Motor Volts - Register #30
Output Voltage to the motor expressed as a percentage of nominal drive voltage.
5.6 Serial Speed - Register #40
This register enables the user to set the serial speed to desired value.
• In tenths of a Hz
• Most significant byte is first, followed by Least significant
• CONTROL OF THE DRIVE SPEED VIA THE SERIAL LINK IS NORMALLY DONE USING THIS PARAMETER.
This register can be written only after enabling parameter writes.
• To use this register, SPEED REFERENCE must be set to SERIAL SPEED REFERENCE by setting bit 8 in
control register #1.
5.7 Unlock Commands - Register #48
Register #48 (Unlock Commands) unlocks commands by using 0000 for the password. If the correct
Programming mode password (C94) is entered then the appropriate programming parameters can also
be accessed (refer to the full parameter protocol specification if access to programming parameters is
required).
5.8 Unlock Parameters - Register #49
Register #49 (Unlock Parameters) unlocks programming parameters for writing when the proper
Programming Password (C94) is entered. Whenever a parameter writing session (where #49 was activated)
is to be ended, register #1 bit 1 (Lock Security) must be asserted. This disables the watchdog and prevents
further write access to Parameter Registers.
5.9 Register Version
Register Version is the number to identify if current version of software has any register changes relative
to previous versions: a register has been added or deleted, a register’s min/max limits have changed, a
register’s function has been changed, or a register’s default value has been changed. Generally it is the
programming parameters that are changed. Typically the Control Registers (
smd Register #1 through #50)
are quite stable.
