Functional Description
DOCUMENT CONTROL NOTE:
The controlled version of this document resides on MedNet. Any printed copy of this document is uncontrolled.
• When the torque increases and reaches a certain "switch off torque", as
the motor reaches the end position, the motor controller detects the stall
position and drives the motor a certain number of steps (e.g. 50 steps) till
it stops.
• During decelration time the stall detection is switched off, as torque differs
to much during deceleration.
• Rubber pieces in the end position support that the motor can be driven
with relatively high speed towards the end position.
• If the torque increases to the "switch-off" torque before the motor is
supposed to reach the stall position, the motor is also stopped. The
software however "knows" that this stop comes too early and issues an
error message (e.g. "IP jam").
NOTE:
The motor curves shown above are simplified. In reality the motor speed can
be reduced just before the stall position, or can even be reduced in several
steps before it stops.
