YASKAWA TM.V1000.01 V1000 Drive Installation & Start-Up Manual (Preliminary 01-19-07)
Description
100% = Max output frequency (E1-04).
Saves the bias value once the frequency
reference is adjusted.
The bias can be set by the user, but will be
disabled under the following conditions:
When none of the multi-function input terminals
are assigned +0 frequency reference bias
function.
When the frequency reference priority has
changed (including multi-step speed).
When both d4-03 = 0 and d4-05 = 1 while the
Up 2 / Down 2 commands are both on or both
off.
When the max output frequency has changed
(E1-04).
When the digital frequency reference has
changed.
• When the Up 2 and Down 2 commands are
enabled, the frequency reference holds the bias
value as the levels for the analog frequency
reference or pulse train frequency reference
change, accelerating or decelerating to the
frequency reference.
• After frequency agree is achieved, the bias
process starts again.
• Enabled only when the analog or pulse train
reference is on.
When d4-06 is greater than d4-08, d4-08
becomes the bias for the upper limit.
Set as a percentage of the max output frequency.
When d4-06 is less than d4-09, d4-09 becomes
the bias for the lower limit.
Set as a percentage of the max output frequency.
d7: Offset Frequency
Use d7 parameters to set the offset frequency.
Added to the frequency reference when one of
the multi-function input terminals is set
(H1- = 44) and switched on.
Added to the frequency reference when one of
the multi-function input terminals is set
(H1- = 45) and switched on.
