Simple Position PID Control
Simple Position PID control is used to keep a stopped load motionless. Simple Position PID control
would be used to keep a stopped elevator from shifting position as the elevator load changed.
Simple Position PID control mode requires the ASD be in PG Vector Feedback mode (F015 = 7 or 8)
and parameters F240, F241, and F243 set to 0.0 Hz.
Simple Position PID control is performed when a position control signal is received. The
terminal assignment for Simple Position PID control is 72. The motor position at the time the command
is received is recorded and used as the position reference point.
The parameters required for Simple Position PID Control setup are listed in the following table.
