ENCODER VERSION COMMANDS
CE +/- 16777215
(Motor Position 
in Encoder 
counts) 
#ACE 
 
*ACE12345 
Current Encoder – Query Only 
- Returns a 16-bit signed value, corresponding to the current 
motor position encoder count. (See Encoder Mode) 
  
EA 0, 1, 2
#AAEA2 
 
Sets Error 
Action to 
Correct Mode 
Error Action – Command or Query 
Default = 2 
- Reads or sets a value that determines the action to be taken 
when an encoder error is found 
0 – The error is reported via the optocoupled output 
1 – The error is reported and the motor is stopped 
2 – The error is reported and the correction move is made 
EI 0, 1
#AEI1 
 
Encoder 
Installed True 
Encoder Installed – Command or Query 
Default = 1 
- Read or set TRUE (1) or FALSE (0) 
EL 0 - 16777215
#AEL400 
 
Sets the 
encoder line 
count to 400 
Encoder Lines – Command or Query 
Default = 400 
- Encoder lines per motor revolution 
- Reads or sets the encoder line count. This is used in 
conjunction with Encoder Mode to calculated motor positions. 
EM 1, 2
#AEM2 
 
Sets the 
Encoder Mode 
to 2 
Encoder Mode – Command or Query 
Default = 2 
- Reads or sets the operating mode of the Encoder Interface IC. 
A value of 1 returns one Encoder Count per Encoder Line. A 
value of 2 returns 2 Encoder Counts per Encoder Line. Only 1 
and 2 are valid. 
EP 0 – 16777215
#AEP10
Error Permitted- Command or Query 
- Reads or sets the maximum error allowed before Error Action is 
taken. Depending on the system configuration, the value is 
given in either Encoder Counts or Steps at the current Step 
Resolution. 
- If the product of Encoder Lines and Encoder Mode is larger than 
the product of Motor Steps and Step Resolution, then the value is 
in Encoder Counts. Otherwise it is in Steps. 
 
Note: The minimum value is the number of the finer resolution 
Encoder Counts or Steps required to make up one unit of the 
coarser resolution. 
ER 0 - 16777215
#AER 
 
*AER5 
 
Error Read – Query Only 
- Returns the current Encoder Error value. If the product of 
Encoder Lines and Encoder mode is larger than the product of 
Motor Steps and Step Resolution, then the error is in Encoder 
Counts. Otherwise it is in Steps. 
GA -
#AGA
Go Target A – Command Only 
This applies to “Go Target B, C, D, E, F, G, H” 
Initiates position move to the corresponding Target Position set 
by TA. 
MF -
#AMF200 
 
Sets Motor 
Fullsteps to 200 
Motor Fullsteps (per revolution) – Command or Query 
Default = 200 
Reads or sets the number of Fullsteps per motor revolution, i.e. 
A 1.8° motor will have a Fullstep count of 200. 
TA -
#ATA100
Target A – Command or Query 
This applies to “Target B, C, D, E, F, G, H” 
- Reads or sets the value of a preset Target Position in Fullstep 
units as an absolute value 
Initiates position move to the corresponding Target Position set 
by TC.
