The speed in rpm is indicated by this parameter, for the selected Pulse Reference input.
When the drive is operating from a pulse reference input and the speed is below 100rpm, this parameter should be used for display
purposes only. Use the speed feedback parameter [3.02] for control purposes if necessary.
The required displacement / movement in position should be entered into Revolutions Error (parameter 13.02) and Position Error (parameter
13.03) using serial communications while parameter 13.10 = 2. The value of parameter 13.02 must be entered first, followed by parameter
13.03. The new value is entered into the buffer when the value of 13.03 has been entered. The drive runs at maximum speed [1.06], while it
is moving into position (see parameter 13.01). The total position displacement / movement is given by:
Position displacement (32 bit) = [13.02] x 65536 = [13.03]
Reference position (parameters 13.22 and 13.23) will be updated with the position displacement. I.e. the appropriate number of counts are
added or subtracted to the reference position.
When reading the position error value from the drive, Position error (13.03) must be read first. When parameter 13.03 is accessed, the value
in Revolutions error (13.02) is frozen until it has also been accessed.
0 - Pulse reference without position control
1 - Pulse reference with position control
2 - Digital reference control via serial communications
Setting this parameter enables the orientation function. This function allows the motor to be stopped at a pre-defined position under analog or
digital speed reference control. The orientation position for the shaft is set in Orientation position reference (parameter 13.13) The range of
parameter 13.13 is 0 to 65535, giving a resolution of 0.011
°
. When the Stop signal is received (i.e. bit parameter 6.34 Run enable is set to 0),
the motor decelerates to the orientation speed set in Orientation speed parameter 13.12. The motor continues rotating in the same direction
until the orientation position is reached within the Orientation acceptance window (parameter 13.14).
