TR-EM-208 TIMING CHART
A: Normal start with forward command. Motor voltage will
rise along accel.-ramp (ramp time A->B adjustable 0-3s).
C: Command aborted, motor voltage drops, motor runs freely
during free deceleration C->E (time adjustable 0-3s).
New commands (D) won’t affect the operation. After free
deceleration, the controller will switch to braking at point E,
in other words motor poles will be short circuited (braking).
With impulse control either “new” command will stop. During
C->E new impulses will not activate a start.
F: Start with reverse command.
G: Stop input changes 0->1 and stops the motor. Motor will
remain in this condition until a new command is assigned.
Start condition setting applies to this moment, restart can be
activated in both directions or only in reverse direction.
H: New start attempt, if old command is still on, new
command will not be executed. When old command exits,
new command must first be set to zero before it will be
executed.
Notice that new stop command will activate only after
stop is first set to zero, in other words changed
0->1 at point I.
J: Start, in which motor will exceed current limit already
during acceleration ramp J->L, at point K current is 1.5 times
adjusted current. Controller starts to limit motor current
by limiting control voltage.
L: Settling time L->M (constant 0.5s), motor current is still
being limited. During this time, if motor current will not
decrease to current limit range, the controller will switch
off motor voltage.
N: If motor current exceeds set limit after acceleration and
settling time, control will be switched off as in point N.
Motor will be stopped and error output and led will be
activated.
O: After over current switch off, restart is possible either in
both directions or with only reverse control, see start
conditions on first page. Restart resets error output and led.
