Using Multi-Step Speed Operation - Omron SYSDRIVE RV Series User Manual

Setting Frequency Reference Using Pulse Train Signals
When b1-01 is set to 4, the pulse train input to control circuit terminal RP is used as the frequency reference.
Set H6-01 (Pulse Train Input Function Selection) to 0 (frequency reference), and then set the 100% reference
pulse frequency to H6-02 (Pulse Train Input Scaling).

Using Multi-Step Speed Operation

With SYSDRIVE 3G3RV series Inverters, you can change the speed to a maximum of 17 steps, using 16 fre-
quency references, and one jog frequency reference.
The following example of a multi-function input terminal function shows a 9-step operation using multi-step
references 1 to 3 and jog frequency selection functions.
Related Parameters
To switch frequency references, set multi-step speed references 1 to 3 and the jog reference selection in the
multi-function contact inputs (any of the terminals S3 to S8). Setting examples are shown below. The unused
terminals need not be set.

Combination of Multi-Function References and Multi-Function Contact Inputs. In the Above
Setting Example
You can change the selected frequency reference by combining the ON/OFF status of S5 to S8 (multi-function
contact input terminals) to set multi-step speed references 1 to 3 and the jog frequency selection. The follow-
ing table shows the possible combinations.
