Host Command Reference

1DI8000 1% Drive at address “1” sends normal Ack (over both ports) in

response to address-speciﬁc set distance to 8000

Bad command Example:

Command Drive Sends Notes

VE200 ?5 Drive sends Nack (over RS-232 port only) in

response to global set velocity to 200 rps; error code 5 is

sent because parameter “200” is out of range

1VE200 1?5 Drive at address “1” sends Nack (over both ports) and error

code in response to address-speciﬁc set velocity to 200 rps

Buffered command Example:

Command Drive Sends Notes

AC10 * Drive sends Exception Ack (over RS-232 port only) in res-

ponse to global set acceleration to 10 rps/s

1AC10 1* Drive at address “1” sends Exception Ack and address (over

both ports) in response to address-speciﬁc set acceleration

Bit 3 - Checksum (use 8-bit checksum)

Not implemented at this time. Call factory for schedule.

Bit 4 - RS-485 Adapter mode

Allows using a drive as an RS-232 to RS-485 adapter by letting the host communicate on an RS-485

network through the ﬁrst drive’s RS-232 port. When the host sends commands with a “~” (tilde) at the beginning

of the command to the ﬁrst drive’s RS-232 port, the command is echoed out of both of that drive’s RS-232 and

RS-485 ports. Drives connected on the RS-485 network will receive the same command with the “~” stripped off.

Without the Bit 4 option (Bit 4=0), a drive will normally echo any addressed command out of the RS-232 port

only, whether the command was received from the drive’s RS-232 or RS-485 port. What the Bit 4 setting does (Bit

4=1), is force the drive to echo commands out the RS-485 port as well, allowing a host that is connected to a drive

through its RS-232 port, to communicate to an RS-485 network of drives.

NOTE: When both Bits 4 and 2 are set (Bit 4=1, Bit 2=1), the host will receive back both the echoed packet

and the acknowledge packet. For example, two drives are connected in an RS-485 network, and they both

have PR command Bits 4 and 2 set. The rst drive, which is also connected to the host via its RS-232 port, is

addressed “1”, and the second drive is addressed “2”. Here is what you will see:

Send data Example:

Command Drive Sends Notes

~2DI8000 2DI8000 Drive at address “1” echoes original command over both

serial ports

2% Drive at address “2” responds with ack.

Request data Example:

Command Drive Sends Notes

~2DI 2DI Drive at address “1” echoes original command over both

serial ports

2DI8000 Drive at address “2” responds with distance

Bit 5 - 3-digit numeric register addressing

Each data register in a drive is normally accessed using its single letter, number, or other ascii character.

With Bit 5 set (Bit 5=1), each of the data registers is instead accessed with a 3-digit number: 000 to 074. (See the

Data Registers section for character and 3-digit numerical assignments). The Bit 5 option implements this speciﬁc
