! Remember that when the amplifier shuts down by exception, the motor will continue to

run by its own inertia unless brakes are used (refer the section Connecting an external

brake).

In order to avoid spurious motor shut downs, always:

- Specify the largest ER[2] you can tolerate

- Leave enough space between VH[2] and HL[2], to allow speed overshoots

- Leave enough space between VL[2] and LL[2], to allow speed overshoots.

14.3 Position Protection

The Harmonica provides two forms of position protections.

- Over error protection.

- Out of position range protection.

The first protection detects a too big position error.

The parameter ER[3] specifies the limit for the position error.

If the absolute value of the tracking error PE exceeds ER[3], The Harmonica issues the

exception MF=0x100 and the power amplifier is shut down.

The second protection detects that the motor position is out of range. If the position

feedback (PX in UM=4, PY in UM=5) is greater than HL[3], or less than LL[3], The

Harmonica issues the exception MF=0x400000 and the power amplifier is shut down.

The position reference and feedback limits are inactive if the position counter counts

modulo, since then the relations "Greater Than" and "Smaller Than" are not well defined.

The table below details the particular cases:

Case Description

UM=1, nonzero XM Torque control, limits taken by the main modulo feedback

UM=2, nonzero XM Speed control by main modulo sensor.

UM=3 No feedback limits since there is no feedback

UM=4, nonzero YM Position control by an auxiliary modulo sensor.

UM=5, nonzero XM Position control by an main modulo sensor.
