Na / Word / - Bit 8, DEGC_ERR
0 RW 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 63 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.
Bit 17, U24V_ERR
This error bit get set if the control voltage, normally at 24VDC, is measured to be
below 12 V (9V on MAC402). The motor must be reset or power cycled to clear this
error. It is considered unsafe to continue, because the electronics may not work
correctly, and may have lost data.
