d1-04 = 40.00 Hz
d1-01, d1-02 and d1-04 are special parameter settings required by the Bypass logic circuit. See Table 5.1.

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 Reference 1, Multi-step
Speed Reference 2, and Jog Frequency.
