• Setting values 10 [Up Command] and
11 [Down Command]
• Setting values 75 [Up 2 Command]
and 76 [Down 2 Command]
• Setting values A [Accel/Decel Ramp

• Setting values 1E [Reference Sample
Hold]
• Setting values 44 to 46 [Add Offset
Frequency 1 to 3 (d7-01 to d7-03)]
Remove the function settings that are not in use.

Fmax] and 62 [Speed Search from
Fref]
• Setting values 65, 66, 7A, 7B [KEB
Ride-Thru 1 or 2 Activate] and 68
[High Slip Braking (HSB) Activate]
• Setting values 16 [Motor 2 Selection]

These settings were entered while H1-xx
= 2 [External Reference 1/2 Selection]:
• b1-15 = 4 [Frequency Reference
Selection 2 = Pulse Train Input]
• H6-01 ≠ 0 [Terminal RP Pulse Train
Function ≠ Frequency Reference]
Set H6-01 = 0
These settings were entered while H1-xx
= 2 [External Reference 1/2 Selection]:
• b1-15 = 3 [Option PCB] or b1-16 = 3
