BLAT (#6) 1: To enable the two-stage backlash acceleration function
<6> Set the observer-related parameters.
The procedure of this adjustment is the same as for
an observer-related parameter adjustment made
with the unexpected disturbance torque detection
function (Subsec. 4.12.1). Make an adjustment
according to steps <4> through <7> of the
parameter adjustment procedure described in (3) in
Subsec. 4.12.1 of this manual. The unexpected
disturbance torque detection function is used, so
that if an adjustment is already made, a
readjustment need not be made.

Observer gain
2050 (FS30i, 16i)
• When HRV1, HRV2, or HRV3 control is used:
[Setting value] No change is required.
• When HRV4 control is used:
[Setting value] 956 → To be changed to 264
1863 (FS15i)
Observer gain
2051 (FS30i, 16i)
• When HRV1, HRV2, or HRV3 control is used:
[Setting value] No change is required.
• When HRV4 control is used:
[Setting value] 510 → To be changed to 35
* When setting an observer gain, follow the settings of other
functions (observer, unexpected disturbance torque detection).
When the two-stage backlash acceleration function is used,
the settings need not be changed.
<7> Adjust observer parameter POA1.
The 2-stage backlash acceleration function takes the friction
torque as an estimated disturbance value by using the observer
circuit and determines the first stage acceleration amount.
Therefore, observer parameter POA1 must be adjusted to obtain
correct acceleration. While observing estimated disturbance
value DTRQ, perform acc./dec. to adjust POA1 to the optimum
value.
