D302 Torque/force too small for movement
The command D3 Commutation Setting was initialized. For this to
occur, the motor must be moving. However, it is not moving.
Cause:
1. The torque is too small to overcome the mechanical resistance
(friction or weight load).
2. The motor is mechanically locked.
Remedy:
1. Raise the value of Parameter CM01, Bipolar Torque/Force Limit
Value until the motor can overcome the mechanical resistance and
turn. Check, using a MOM command, if the Torque/Force Limit Value
is too small.
2. Release pinched cables/wires. If necessary, also check the brake.
D400 Command Move to Positive Stop
Using the "PFA“ or "PFI“ commands, the move to positive stop command
is activated. In this process, encoder monitoring is turned off, which would
result in a drive error message if the drive were blocked because of a
positive stop.
Cause:
The movement to positive stop was activated using the "PFA" or "PFI"
commands.
See also Section "Movement to Positive Stop."
"d4" Display
D500 Command Detect Marker Position
An unknown command was invoked.
Cause:
Firmware malfunction.
D501 No incremental measuring system
Cause:
The command was initialized for a measuring system that does not have
any real reference marks. Examples are measuring systems like DSF,
EnDat, SSI or resolver measuring systems.
Remedy:
Check if the correct encoder is set in Parameter C009, Homing
configuration.
Implement an encoder system with real reference marks.
