Data byte 1
mode: 0 – watchdog off, 1 – disable the amplifier, 2 – stop smoothly and disable the
amplifier, 3 – stop smoothly.
Data byte 2
watchdog timeout in multiples of 8192 microseconds.
Description
This command sets the watchdog mode and timeout. The watchdog is refreshed by any command sent to
the driver. Upon expiration, the watchdog can disable the amplifier, stop smoothly and disable the
amplifier, or stop smoothly and keep the amplifier enabled. After the watchdog expires, the drive stops
executing any motion commands. This command should be sent again to reset the watchdog.
The watchdog status can be obtained using Read Status or Define Status commands with bit 12 set to 1.
If the watchdog is not activated, the status will be 65535 (0xFFFF). If the watchdog has expired, the status
will be 0. Any other value means that the watchdog is working and represents the remaining time before
the watchdog expires in multiples of 8192 microseconds.
Sub-command
0x10
Set motor error limit.
Data bytes 1 and 2
motor error limit.
Description
In dual loop mode, after power up, the motor error limit is set to the same value as the master error limit.
Set gain commands also sets the motor error limit to the same value as the master error limit. This
command can be used to set the motor error limit.
Hard Reset
Command value:
0xF
Number of data bytes:
0
Command byte:
0x0F
Description:
Resets the control module to its power-up state. No status will be returned. Typically, this command is
issued to all the modules on the network, although if the baud rate is set at the default, it is possible to
reset and re-initialize the addresses of a contiguous sub-chain of modules.
Hard reset command sent at address 0xFF resets the controller even if its group address is different than
0xFF.
