4.6.8. Spindle orientation
When this mode (12) is selected it becomes operational when b40.2=1. The motor reaches
the speed in Pr50 on the ramps in Pr52. It now spins at constant speed until it reaches the
position set in Pr54; at this point the position loop is closed.
PARAMETERS FOR OPERATING MODE 12
Pr50 Maximum speed during spindle orientation . Unit=rpm, default=200,
range=0..500. This parameter makes it possible to limit maximum motor speed
during spindle orientation.
Pr51 Reserved.
Pr52 Deceleration ramp . Unit=s/krpm, default=500, range=2..30000, resolution=1
thousandth of a second. When the spindle orientation command is set (b40.2=1)
deceleration required of the motor can be limited by this parameter so that a change
of 1000 rpm takes Pr52 thousandths of a second.
Pr53 Reserved.
Pr54 Motor shaft position for spindle orientation . Unit=steps, default=0, range=0..4095.
One revolution of the motor shaft corresponds to 4096 steps.
Pr56 Servo-error window . Unit=steps, default=100. If the absolute position error is
greater than the value set in Pr56, b70.5 is set to 1.
Pr57 Position control loop proportional gain . Default=100, range = 0..32000.
Pr58 Reserved.
Pr59 Reserved.
b70.5 Servo-error . b70.5 is set to 1 if the absolute position error is greater than the value
in Pr56, otherwise it is set to zero.
4.7. Block diagrams
The main block diagram provides a graphic description of how to use the drive. Each
rectangular block represents one or more read/write parameters, each rhomboid shape
represents read-only parameters. In the diagram there are other functional blocks such as:
greater than..., equal to, the smallest among..., logical and/or; we have used standard symbols
for all these blocks. Binary parameters are shown as switches and the position depicted is the
default value.
