Note:

Simultaneously assigning KEB Ride-Thru 1 and KEB Ride-Thru 2 to the input terminals will trigger an oPE03 error.

Setting 67: Communication Test Mode

The drive has a built-in function to self-diagnose serial communications operation. The test involves wiring the send and

receive terminals of the RS-422/RS-485 port together. The drive transmits data and then confirms that the communications

are received normally.

Refer to Self-Diagnostics on page 263

for details on how to use this function.

Setting 68: High Slip Braking

Closing an input programmed for this function triggers High Slip Braking (available only in V/f control mode). After starting

HSB, bring the drive to a complete stop and remove the HSB command before restarting.

Refer to n3: High Slip Braking

(HSB) and Overexcitation Braking on page 124

.

Setting 69: Jog 2

The Jog 2 function applies to 3-Wire control only. If a digital input is configured as Jog 2 (H1-oo = 69) when the drive is

not in 3-Wire Control, an oPE03 fault will occur.
The Jog 2 input causes the drive to ramp to the Jog Frequency Reference (d1-17) in the direction dictated by the Fwd/Rev

input of the 3-Wire Control mode. Acceleration to and from the Jog Frequency Reference is determined by the active Accel/

Decel parameters.

Setting 6A: Drive Enable

A digital input configured as a “Drive enable” (H1-oo = 6A) will prevent the drive from executing a Run command until

the input is closed. When the input is open, the HOA keypad will display “dnE” to indicate that the drive is disabled.
If a Run command is enabled before the terminal set for “Drive enable” closes, then the drive will not run until the Run

command is cycled (i.e., a new Run command is required). If the input is opened while the drive is running, the drive will stop

according to the stop method set to b1-03 (

Refer to b1-03: Stopping Method Selection on page 26

).
