Settings 7A and 7B: KEB Ride-Thru 2 (N.C., N.O.)
An input terminal set to 7A or 7B can trigger Single Drive KEB Ride-Thru during deceleration. L2-29 is disregarded if this
is enabled.

Setting 7A (N.C.)
Setting 7B (N.O.)
Note:
Simultaneously assigning KEB Ride-Thru 1 and KEB Ride-Thru 2 to the input terminals will trigger an oPE03 error.
Setting 80: HAND Mode
Closing this input will put the drive in HAND Mode.
If this contact is closed within one second of power-up, the drive will honor the utility delay time.
Note: When inputs 80 and 81 are closed simultaneously, input 80 has priority and P5-01 determines the frequency reference.
Setting 81: HAND Mode 2
Closing this input will put the drive in HAND Mode using P5-05 as a frequency reference.
If this contact is closed within one second of power-up, the drive will honor the utility delay time.
Note: When inputs 80 and 81 are closed simultaneously, input 80 has priority and P5-01 determines the frequency reference.
Settings 83, 84, and 85: Alternate Multi-step Setpoints
These setpoint selections are different from Multi Setpoints 1 and 2 (H1-oo = 8D/8E) in that each input is dedicated to a
setpoint instead of being a binary selection.
Table 5.23 shows active setpoints based on the Alternate Multi-Setpoint Selections (H1-oo = 83 to 85):

Setting 88: Volute-Thermostat (N.O.)
Closed: Drive will trip on "VLTS - Volute-TStat Flt".
Open: Thermostat fault not active.
Note: Assigning both 88 and 89 to input terminals will trigger a VLTS-Volute-TStat Flt.
Setting 89: Volute-Thermostat (N.C.)
Closed: Thermostat fault not active.
Open: Drive will trip on "VLTS - Volute-TStat Flt".
Note: Assigning both 88 and 89 to input terminals will trigger a VLTS-Volute-TStat Flt.

• Accelerates (increases the bias) while the Up 2
terminal is closed.
0 1 -- • Decelerates (decreases the bias) while Down 2 is
closed.
• Otherwise operates at the frequency reference
0 • When Up 2 is enabled, drive accelerates to the
frequency reference plus d4-03 (increases the bias
for d4-03).
Value • When Down 2 is enabled, drive decelerates to the
other -- frequency reference minus d4-03 (decreases the
1
than 0 bias for d4-03).
• If the frequency reference changes for more than
d4-07 during accel/decel, bias value is held until the
output frequency meets the reference (speed agree).

If the bias is constant for 5 s, it is
saved to parameter d4-06. The
frequency reference cannot be
overwritten, so only the bias is
saved.
