US - Basic Setup Parameters
Speed Input(s), Analog or Serial pattern
May be given with the direction input, before, or after.
Acceleration to selected speed will begin after LT01 Brake Release Delay
and LT03 Speed Start Delay
For external profile pattern from Analog or Serial speed control, LT03
Speed Start Delay will expire automatically when command becomes
non-zero.
Pretorque stage is exited and the acceleration/run speed stage begins;
LC03, LC08, and LC11 speed control gains are active
After an initial speed is selected, any higher speed selected will be ignored
until zero speed is selected.
Stopping:
When a speed less than the run speed is selected (eg. leveling), the
acceleration/run speed stage is exited and the deceleration/leveling stage
begins; LC04, LC09, and LC12 speed control gains are active.
If all speed inputs or direction are dropped deceleration to zero speed will begin.
When zero speed command is reached and direction is dropped, the LT10
Brake Drop Delay timer begins. After the timer expires:
The Brake Control output is deactivated.
The LT12 Current Hold Time begins. As the timer expires:
The Drive On output deactivates.
The LT13 Current Ramp Down Time begins. After the timer expires:
The output current will have reached zero and the modulation
will be turned off. The Drive Enable, I7, can be dropped.
Dropping the Drive Enable before the LT12 + LT13 timers have
expired and the current has ramped down to zero will shut off the
output current and modulation immediately, which may cause
an abnormal stopping sensation.
Dropping the Drive Enable while outputting current will generate
a Drive Enable Dropped Event.
