r8 A/ B Out of Range
r8 Displayed in sequence
D e finit ion A/ B Out of Range
Type Fault
Act ive disa ble No
M e ssage # FLT 22
Descr iption
Feedback analog signal is out of range. This fault is
relat ed to resolver and sine encoder feedback. The drive
checks that the am plitudes of the sine and cosine signals
are correct , based on the calculation sin2 + cos2 = 1
This fault disables the drive.
Action required
Refer to the section Sine Encoder and Resolver
Diagnostics.
Check the amplitudes of the sine and cosine signals.
r9 Encoder Sim ulation Frequency Too High

D e finit ion Encoder Sim ulation Frequency Too High
Type Fault
Act ive disa ble Yes
M e ssage # FLT 15
Descr iption
The computed equivalent encoder output frequency
exceeds the upper lim it for this signal, which is 4 MHz.
This fault disables the drive.
Action required
Check the parameters used for setting up the equivalent
encoder output. If using a sine encoder, check the
ENCOUTRES param eter settings.
