Command Descriptions
AC – Acceleration
Sets accel rate in rev/sec/sec. Sending AC with no number causes drive to respond with present
accel rate. Range is 1 – 3000.
Affects: FL, FS, FP, SH
See also: DE
Example:
You send
Drive sends
AC100 nothing
AC AC=100
AM – Acceleration Maximum
Sets maximum accel rate in rev/sec/sec. This value is used if a move encounters an end of travel limit.
It is also used by the ST and SK commands if they interrupt a move. Sending AM with no number
causes drive to respond with present accel rate. Range is 1 – 3000.
Affects: FL, FS, FP, SH
See also: AC, DE
Not available with older firmware.
Example:
You send
Drive sends
AM500 nothing
AM AC=500
BR – Bit Rate
Changes the serial port bit rate. This can be used to increase the communication speed between the
host controller and the Si™ drive. You must change the bit rate of the host controller after sending this
command or subsequent command will not be understood by the drive. Version 1.31 of the SCL Setup
Utility has adjustable bit rates and is a usefull tool for experimenting with bit rates. Drive powers up to
9600 bits/second.
Not available with older firmware. Some drives do not support BR3 (38400 bps).
Bit Rate Codes
1 = 9600 (about 1000 characters per second)
2 = 19200 (2000 chars/sec)
3 = 38400 (4000 chars/sec)
BS – Buffer Status
Drive tells you how much space is available in the command buffer.
Example:
You send
Drive sends note
BS BS=128 there is room for 128 additional characters
CC – Change Current
Changes current setting of drive. Also allows you to request present current setting. When you set the
current with the CC, the idle current is automatically set to 50%.
Affects: FL, FS, FP, SH, WI (jogging)
