PROBLEM CAUSE / VERIFICATION SOLUTION
Torque Limit is set to zero.
Verify Torque Limit setting by Status Panels Æ
Numeric Status Æ Axis Parameters Æ Limit
Parameters Æ Plus/Minus Torque Limit
Assign the appropriate Torque Limit value.
Example: TLM X1 indicates torque is limited to 10% of drive
motor capacity for axis X.
Feedback device counts are missing Check the feedback cable and connections.
Check the amplifier to send back correct signals.
Improper operation
(for PCI controller cards) Incorrect termination /
pull-up resistor.
Check that the correct type of resistor (termination or pull-up)
is installed for the type of encoder being used.
Incorrect tuning gain settings. Check tuning gain settings. Servo motors make
audible noise
Incorrect motor commutation. Verify drive settings, motor connections.
Incorrect move mode, absolute vs. incremental Make sure the move mode is correct ABS vs. INC. Incorrect commanded
distance or position
Incorrect PPU setting. Correct PPU setting for position or distance.
Check the commanded velocity by going into the
correct PROG level. Type (for example) VEL or JOG
VEL X.
Assign the appropriate velocity value. Example: VEL 10 or JOG
VEL X 10.
Incorrect commanded
velocity
Check the feedrate override by going into the correct
PROG level. Type FOV.
Assign the appropriate feedrate override value. Example: FOV
1 indicates a master feedrate of 1.
Incorrect torque limit Verify Torque Limit setting by Status Panels Æ
Numeric Status Æ Axis Parameters Æ Limit
Parameters Æ Plus/Minus Torque Limit.
Assign the appropriate Torque Limit value. Example: TLM X1
indicates torque is limited to 10% of drive motor capacity.
“Not valid while in
motion” message
received
Tried to enable/disable axis while motion is
commanded.
Check if axis is making coordinated motion: Status Panels ÆBit
Status Æ Master Flags. (Each master is indicated by Bit “In
Motion.”)
Check if the axis is making jog motion: Status Panels Æ Bit
Status Æ Axis Flags Æ Primary Axis Flags. (Each axis is
indicated by Bit “Jog Active.”)
