VarCom Reference
Type
: switch variable, switch mode variable, (standard) variable, or
vector variable. Switch variables can be toggled between two
different states (0/1, on/off, etc.). Switch mode variables are state
variables used to select one of more than two states (for example,
opmode is a switch mode variable that selects one of 6 Opmodes:
0-4, 8). Standard variables are set to an integer value within a given
range.
Vector variables are special variables that are used for the
Advanced Pole Placement compensator (COMPMODE=3) and
require the use of the REFRESH command when changed.
All variables are classified as read-only (R) or read/write (R/W).
Range
: defines the range of valid values for the variable.
Units:
defines the units of the variable. Note that to get the final
value of the variable, including its units, you multiply its value by its
units. Example: the units of MICONT are “amps * 0.1.” If MICONT =
200, then its value is 200 * amps * 0.1 = 20 amps.
Default
: defines the default value of the variable. If this field says
“motor data,” then the default value is entered from a motor data file
(using
MOTIONLINK
’s Motor Configuration Screen) or a motor data
sheet. Most variables are reset to their defaults by using the
RSTVAR command.
Opmodes:
(0-4, 8) indicates in which operational modes
(opmodes) the variable is used (see the description for the variable
OPMODE
). Most variables can be set in any opmode, but they only
have an effect in the opmodes listed here.
Drive Status:
(en, dis, or EN/DIS) indicates the drive state in which
the command can be used (en = enabled; dis = disabled; EN/DIS =
either).
EEPROM:
(Yes or no) specifies whether or not a variable can be
stored in non-volatile memory (EEPROM). If a variable is stored in
EEPROM, it is “remembered” by the SERVO
STAR
when the drive
is powered down and back up. See the
SAVE
command for more
information.
