Additional Information
Speed Selection Error
The Speed Selection Error event will occur when no speed command input is given within a certain
time period at the beginning of a run with US04 Control Type = Binary Speed (1), Digital Speed (0), or
Serial Binary Speed (6). The speed inputs must be selected before the expiration of LT03 + 20 sec-
onds. Toggling the speed before this does not reset the timer and does not have any effect; the speed
command must be present at the expiration of the timers.
The timer is dened as:
t = LT03 + 20.0 seconds
= Speed Start Delay + 20.0 seconds
Default = 0.70s + 20.0s = 20.7s
The default setting for programmable digital inputs (LI04-11) is No Function (Off).
Likewise, for Serial Binary Speed control (US04 = 6) the (Fb21-27) serial inputs are
also set as No Function (Off) by default. The inputs must be assigned accordingly for
Speed Selection (27).
Serial Command Speed Error
The Serial Command Speed Error event will occur when no speed command is given within a certain
time period at the beginning of a run with external prole pattern generation US04 Control Type = Se-
rial (4,5) modes. The speed pattern must be received before the expiration of LT03 + 20 seconds.
The timer is dened as:
t = LT03 + 20.0 seconds
= Speed Start Delay + 20.0 seconds
Default = 0.70s + 20.0s = 20.7s
If a speed command is detected during the LT03 Speed Start Delay, the timer will automatically expire
at the phase of the prole where pretorque speed control gains (LC05, 10) are active and the drive will
switch to the acceleration phase (LC03, 08, 11).
This timer is not active during an inspection run. Speed Selection Error will not
occur.
This timer is not active during an inspection run. Serial Command Speed Error will
not occur.
