Parameter and Variable Descriptions
Firmware Revisions 4.72 & 5.32
Important Notice : With the introduction of the new 18-pulse control boards, the Drive Control firmware has
been split into two parallel versions. Firmware revisions below 5.00 can only be used in the original Drive
Control board 80165-108-51. Firmware revision 5.00 and above can only be used in the new 18-Pulse Drive
Control board 80190-118-51. Although every effort has been made to make them as similar as possible, the
two versions of firmware are definitely not interchangeable and will not function if installed in the wrong
type of Drive Control board.
The drive control firmware provides over two hundred parameters and variables that are accessible to the user.
Parameters are user adjustable constants such as ramp times or trip levels that are saved in nonvolatile (EE)
memory when the control power is off. Variables are values such as speed reference or current feedback that
cannot be changed by the user. Parameters and variables are grouped and described separately. For example,
there is a group of parameters for the speed control function and there is also a separate group of variables for
the speed control function.
Parameter Descriptions
The drive parameters are described in this section. The parameter descriptions are arranged in the functional
groups used by the programming terminal. Each description begins with the full name of the parameter,
followed by the name displayed on the programming terminal. The linear number of the parameter is given
followed by the minimum and maximum values showing the position of the decimal point and the units if
applicable. Next is the default value that is assigned when a parameter initialization is performed. Finally, there
is a short description of the function of the parameter. Unless stated otherwise, all parameters are saved in
nonvolatile memory.

Contactor Configuration [Contactor config]
Linear number:
1
Minimum value: 0
Maximum value: 7
Default value: 0
This parameter specifies the contactor configuration, specifically under what conditions the input and output
contactors will be open. The possible contactor configurations specified by this parameter are:
Input Contactor Output Contactor
0 Open when not running Open when not running
1 Open for all faults Open when not running
2 Open when not running Open for all faults
3 Open for all faults Open for all faults
4 Open when not running Open when not running
5 Open for critical faults only Open when not running
6 Open when not running Open for all faults
7 Open for critical faults only Open for all faults
Critical faults are line overcurrent, DC link overcurrent, and line overvoltage. If an input or output contactor is
not provided, the "close contactor" discrete output should be connected to the corresponding "contactor closed"
discrete input.
Provision for keeping the contactors closed for all except critical faults was added in Rev 4.40/5.10.
