➄
Software Commands 67
this command if you had previously disabled the RS-232C interface with the Disable
Communications Interface (F) command. If several units are using the same
communications interface, the E and F commands can help streamline programming.
Command Description
F Disables all units (axes) on the communications interface
1E Enables serial interface on Device 1
4E Enables serial interface on Device 4
A1Ø Set acceleration to 10 revs/sec
2
V5 Set velocity to 5 revs/sec
D5ØØØ Sets distance to 5000 encoder counts
G Executes the move (Go—only axes 1 & 4 will move)
ER—Encoder Resolution
❏
Command Type: Set-up
❏
Valid Software Version: A
❏
Syntax: <a>ERn
❏
Units: n = encoder counts/rev
❏
Range: n = 400 - 65,532
❏
Default Value: 4000
❏
Attributes: Buffered,
❏
Response to aER is *ERn

The encoder resolution defines the number of encoder counts the controller will see per
revolution of the motor. The number of lines on an encoder should be multiplied by 4 to
arrive at the correct ER value per revolution of the motor. (In other words, one line of an
encoder will produce 4 encoder counts due to quadrature detection)
Command Description
ER4ØØØ Sets encoder resolution to 4000 encoder counts per 1 motor revolution
1ER Reports Encoder Resolution (*ER4000)
F—Disable Communications
❏
Command Type: Programming

Units: N/A

Default Value: None

Attributes: Immediate

The Disable Communications (F) command is useful when you are programming multiple
units on a single interface. Axes that are not intended to process global commands should
be disabled using device specific F commands. This allows you to program other units
without specifying a device identifier on every command. If you do not disable other units
in a daisy chain, uploading programs may cause other units on the daisy chain to perform
uploaded commands.
Command Description
1F Disables the communications interface on unit #1
3F Disables the communications interface on unit #3
G All controllers (except 1 & 3) will execute a move
