0: Holds the bias value when Up/Down 2
reference is on or off.
1: When the Up 2 reference and Down 2
reference are both on or both off, the applied
bias becomes 0. Currently selected accel/ decel.
times are used.
Enabled only when d4-03 = 0.
The Up/Down 2 bias value is saved in d4-06
once the frequency reference is adjusted. It is
limited by d4-08 and d4-09.
The bias can be set by the user, but will be
disabled under the following conditions:
• When none of the digital inputs are assigned to
Up2/Down2 commands.
• When the frequency reference source has been
changed (including multi-step speed).
• When both d4-03 = 0 and d4-05 = 1 and the
Up 2 / Down 2 commands are both on or both
off.
• When the max output frequency E1-04 has
changed.
When the digita
When during Up2/Down2 the frequency
reference value from analog or pulse input
changes for more than the level set in d4-07, the
bias value is hold and the referecne is changed to
the new value.
After the speed reaches the frequency reference
the bias hold is released.
(Works with frequecny reference from analog or
pulse input only)
Sets the upper limit for d4-06 in percent of the
maximum output frequency E1-04.
Sets the lower limit for d4-06 in percent of the
maximum output frequency E1-04.
