Communication protocolBaud rate 115200, data bits 8, stop bit 1, no parity bit:
A command begins with instruction code and ends with a carriage return '\r' (ASCII 0x0D). Multiple commands can be transmitted with a semicolon as separator. For example, single command: 'help\r' or multiple commands 'ac=100;ac;dc\r'.

There are 'read' and 'write' command types. 'Read' command only gets a value or parameter, 'write' command sets a parameter and shows a current value of the parameter in the response.

For example, read command (get current acceleration):
controller read command: 'ac\r'
controller response: 'ac=1000\r'

For example, write command (set current acceleration to 2000 steps/sec2):
controller write command: 'ac=2000\r'
controller response: 'ac=2000\r'

Commands overview(R=read command, W=write command):
commandR,Wdescription and examples
hp, helpRdisplay a help screen with a list of possible commands
no additional values;
vr, verRget current software version
no additional values;
command: vr\r
response: vr=FIMC1-3.17.20.1\r
rsWreset the device, all parameters will be set to default values
no additional values;
command: rs\r
response: rs=1\r
mmR,Wget/set current motor mode
allowed values:
0=halt: if a motion is currently in progress (motor runs), it will be halted immediatly;
1=position mode: in this mode motor position can be controlled with tp (target position) parameter;
2=velocity mode: motor runs with constant velocity sp and rotation direction rd;
3=soft stop mode: if a motion is currently in progress (motor runs), it will be stopped with a deceleration dc;
command (read): mm\r
response (read): mm=0\r
command (write): mm=1\r
response (write): mm=1\r
msR,Wget/set current microstepping resolution
allowed values:
1=full step (default);
2=half step;
4=quarter step (only FIMC1V3X);
16=sixteenth step (only FIMC1V3X);
command (read): ms\r
response (read): ms=1\r
command (write): ms=2\r
response (write): ms=2\r
cpR,Wget/set current motor position (position mode mm=1)
allowed values: –2147483648 to 2147483647;
command (read): cp\r
response (read): cp=-321654\r
command (write): cp=987321\r
response (write): cp=987321\r
WARNING: if you change current motor position (cp) in position mode (mm=1), motor will run to the target position (tp).
To change current and target position at a time use ct command.
tpR,Wget/set target motor position (position mode mm=1)
allowed values: –2147483648 to 2147483647;
command (read): tp\r
response (read): tp=-321654\r
command (write): tp=987321\r
response (write): tp=987321\r
WARNING: if you change target motor position (tp) in position mode (mm=1), motor will run from the current (cp) to the target position (tp).
To change current and target position at a time use ct command.
acR,Wget/set motor acceleration in steps/sec2

QUICK START GUIDE
1. switch on;
2. transmit setup commands:
'ci=0;cr=10;sp=400;mm=1\r'
3. wait for response:
'ci=0;cr=10;sp=400;mm=1\r'
4. transmit commands:
'tp=100\r'
5. wait for response:
'tp=100\r'
6. motor makes 100 steps forward!
7. transmit commands:
'tp=0\r'
8. wait for response:
'tp=0\r'
9. motor makes 100 steps backward!
