Command, function and parameter description
Section 6-3
Syntax:
FREE
Description:
The FREE function returns the remaining amount of memory available for
user programs and Table array elements.
Precautions:
Each line takes a minimum of 4 characters (bytes) in memory. This is for the
length of this line, the length of the previous line, number of spaces at the
beginning of the line and a single command token. Additional commands
need one byte per token; most other data is held as ASCII.
The MC Unit compiles programs before they are executed, this means that
twice the memory is required to be able to execute a program.
Example:
>> PRINT FREE

FS_LIMIT
Type:
Axis Parameter
Alternative:
FSLIMIT
Description:
The FS_LIMIT axis parameter contains the absolute position of the forward
software limit in user units.
A software limit for forward movement can be set from the program to control
the working range of the machine. When the limit is reached, the MC Unit will
decelerate to zero, and then cancel the move. Bit 9 of the AXISSTATUS axis
parameter will be turned ON while the axis position is greater than FS_LIMIT.

FWD_IN
Type:
Axis Parameter
Description:
The FWD_IN axis parameter contains the input number to be used as a for-
ward limit input. The number can be set from 0 to 7 and 18. Range 0 to 7 is
used to select one of the MC Unit inputs. Defining value 18 will select the
Servo Driver’s POT (Forward drive prohibited, CN1 pin 42) input. As default
the parameter is set to –1, no input is selected.
If an input number is set and the limit is reached, any forward motion on that
axis will be stopped. Bit 4 of the AXISSTATUS will also be set.
Note This input is active low.

FWD_JOG
Type:
Axis Parameter
Description:
The FWD_JOG axis parameter contains the input number to be used as a jog
forward input. The input can be set from 0 to 7. As default the parameter is set
to –1, no input is selected.
Note This input is active low.

GET
Type:
I/O Command
Syntax:
GET
[
#n,
]
variable
Description:
The GET command assigns the ASCII code of a received character to a vari-
able. If the serial port buffer is empty, program execution will be paused until a
character has been received. Channels 5 to 7 are logical channels that are
