The Drive can be programmed to utilize digital inputs to change between four presets speeds and a jog speed. It is a two-step
process to set the Drive up for preset speeds. First, d1-01 through d1-04 and d1-17 must be programmed with the desired
preset speeds and the desired jog speed, respectively. Next, up to three of the Drive's digital inputs (Terminals S3 through S7)
need to be programmed (via parameters H1-01 to H1-05) and wired (to normally open contacts) as Multi-step Speed Refer-
ence 1, Multi-step Speed Reference 2, and Jog Frequency.

The Jog Frequency input is given priority over the multi-step speeds.
As shown in the above table, it is possible to use analog inputs in place of Frequency Reference 1 and Frequency
Reference 2.
If b1-01= "1: Terminals" then the analog input A1 will be used instead of Frequency Reference 1 for the first preset speed.
If b1-01= "0: Operator", then Frequency Reference 1 will be used.
If H3-09= "2: Aux Reference" then the analog input A2 will be used instead of Frequency Reference 2 for the second
preset speed. If H3-09 ≠ 2 then Frequency Reference 2 will be used.
The programming of d1-01 through d1-04 and d1-17 will be affected by the setting of o1-03. The programming
IMPORTANT
of these parameters will be in the units specified by Display Scaling parameter (o1-03).
