Bit 6, DEC_FLAG

Set when the motor is decelerating. Please see the description for
ACC_FLAG above to understand the behaviour with negative velocity.

Bit 7 PLIM_ERR

Set when one of the software position limits in Reg28 and Reg30 have
been exceeded. Note that there is an option to temporarily disable
position limits to be able to be move inside the position limit range
again.

Bit 8, DEGC_ERR

Temperature error; set when the value in Reg29, DEGC, exceeds the
value in Reg31, DEGCMAX.

Bit 9, UV_ERR

Under voltage error; can be set when either the AC sense detects
missing

230 or 120 V AC input, or when the DC bus voltage get below

a threshold voltage of approximately 80 V DC. Note that this error will
only get set if bit 0 in Reg23, UV_HANDLE, is set.

The AC sense input

is not used with MAC402.

Bit 10, UV_DETECT

Reflects the current status of missing AC input or low DC bus voltage,
on the same condition as UV_ERR above. The bit will be cleared
when the under voltage condition is no longer present for about one
second. Note that there is a hysteresis built-in, so the DC bus voltage
must be 1.25 times higher than the cut-off voltage threshold before the
under voltage condition is cleared.

Bit 11, OV_ERR

Overvoltage error; gets set when the DC bus voltage is measured to
be above 450 V for MAC400 and MAC800, or 1000 V DC for
MAC1500 and MAC3000, or 54 V DC for MAC402. Overvoltage often

comes when the motor is braking a large inertia and the internal or
external power dump/brake resistor can no longer accumulate the
energy. It can also come from connecting a too high AC or DC supply
voltage, perhaps by connecting 230VAC to the 120 VAC input on
MAC400.

Bit 12, IPEAK_ERR

A much too high current was measured in one or more of the motor
phases. This can happen if the supply voltage is too low relative to the
rotational speed. It can also happen in more extreme short-time
overload conditions. This error requires a reset or power cycling of the
drive since it cannot be cleared using the normal Clear Errors
mechanisms.

Bit 13, SPEED_ERR

The velocity was measured to be higher than a limit for an average of
16 samples. This limit is normally 3600 RPM for MAC800, MAC1500
and MAC3000, and

it is 4300 RPM for MAC400 and MAC402. There is

an option in later firmware to increase the speed error limit to 4000
RPM on MAC800 for shorter movements.

Bit 14, DIS_P_LIM

This bit is not an error or status bit,

but rather a command bit.

When this is set, the motor will stay in an active mode and allow
moves even though one of the software position limits defined by
Reg28 and Reg30 is exceeded. The bit is automatically cleared once
the position gets inside the valid position range.

Bit 15, INDEX_ERR

The bit is set if an encoder error is detected. This can be a real
encoder hardware error or excessive electrical noise. The motor must
be reset or power cycled to clear this error.

Bit 16, OLDFILTERR

This bit is no longer used. It could detect if a previous version of the
velocity filters was found, or loaded, that did not work with newer
firmware.
