Network Communication Gear Ratio Adjustment
Allows gear ratio adjustment via network communication. The total gear ratio
adjustment is the sum of the analog, digital, MOP and network communication
ratio adjustments. Data is interpreted as signed, so the adjustment can be set
from –327.68% ~ 327.67%.
Note: The ENTER command is not required when writing to this register.
1 = 0.01%
61DH
Network Communication Advance/Retard Counts
Allows for advancement/retardment of the follower drive via network
communication. Data is interpreted as signed, so the advance/retard counts
can be set from –32768 ~ 32767. This is set in quadrature follower encoder
counts. After this register is set, its data returns to zero automatically.
Note: ELS modes only.
Note: The ENTER command is not required when writing to this register.

Follower Sel Err
There is a problem with the
configuration of the
Follower function.
ƒ P1-01 = 4, 5 (ELS
modes) and the PG-W2,
PG-Y2, or PG-Z2 is not
installed.
ƒ P1-01 = 1, 2, 3 (Speed
Follower modes), the
control mode is V/f w/
PG or Flux Vector and
the PG-W2, PG-Y2, or
PG-Z2 is not installed.
ƒ P1-01 = 1, 2, 3 (Speed
Follower modes), the
control mode is V/f or
Open Loop Vector and
one of the following
option cards is not
installed: PG-B2, PG-
T2, PG-X2, PG-W2, PG-
Y2, or PG-Z2.
Install the appropriate
encoder (PG) option card
for the control mode and
follower mode selection.
