Alarm: Position Deviation Limit Exceeded 217
User Guide v 2.3 — September 2015 UltraSync-E, If Equipped
16.8.2 Alarm: Position Deviation Limit Exceeded
This fault occurs when the valve stems position deviates from set position, by more than the
value of the Position Alarm Window setting. The alarms can be cleared but may reappear
immediately or during the next valve stem movement if the problem still remains.
Possible causes for this fault include:
• Opening or Closing Force Limit are set too low
• Position Monitoring Window is set too small
• Resin in the system is too cold or the temperature zone setpoints are set too low
• A physical obstruction of the valve stem plate
• Damaged component
98 Motor over temperature Let motor cool down. Increase cycle time (cycle
time should not be less than 3sec).
99 Error I
2
t > 100% Let motor cool down. Increase cycle time (cycle
time should not be less than 3sec).
115 Cable break encoder 1 Check to make sure black encoder cable is
connected between motor and drive and not
damaged.
123 Field angle error Check black encoder cable for shield damage.
146 Encoder module 1 is missing Module A in the drive is missing or faulty.
Replace if necessary.
192 Position deviation dynamic Motor position has exceeded its control
position. Make sure injection is not occurring
until stems are in the open position (do not
inject while stems are opening). Try decreasing
hold pressure.
193 Position deviation static Motor position has exceeded its control
position. Make sure injection is not occurring
until stems are in the open position (do not
inject while stems are opening). Try decreasing
hold pressure.
200 Homing necessary and not yet
executed
Perform calibration. Cycle power to drive.
208 Drive is blocked Motor is blocked/stalled that was not detected
by obstruction detection software or torque
limit exceeded for a prolonged period of time.
Perform calibration. Check for obstruction in
valve stem actuation system. Cycle power to
drive.
