Function:
Function:
[0 - 65535 ] Readout parameter to log events if
the Back EMF has been enabled or
disabled. The range of the read-out
parameter is between [0x0 -0xFFFF]
hex. The value indicates the bit
pattern to identify the current state
of Back EMF in the drive.
Bit 1 is set: When Back EMF is
enabled the bit is set to 1. Once
enabled the Back EMF cannot be
reversed.
Bit 1 and Bit 2: Motor frequency
exceeded Back EMF limitation. Bit 2
can be reversed.
Bit 1, Bit 2, and Bit 3: The drive has
been coasted as motor frequency
exceeded the Back EMF limitation.
Bit 1, Bit 2, Bit 3, Bit 4: The drive
has generated an over-voltage
alarm because the drive has
coasted as the motor frequency
exceeded Back EMF limitation.
