Use an Analog Input as Reference 1 and 2 This section gives information about the procedures to set these examples: Multi-Step Speed 6 (6 types of frequency references) When you set the voltage input of analog inputs from terminals A1 and A3 to -10 V to +10 V Procedure Configuration Parameter Task Contents 1 Reference 1 Set b1-01 = 1 [Frequency Reference Selection 1 = Analog Input]. Set H3-02 = 0 [Terminal A1 Function Selection = Frequency Reference]. Set H3-01 = 1 [Terminal A1 Signal Level Select = -10 to +10V (Bipolar Reference)]. 2 Reference 2 Set H3-06 = 2 [Terminal A3 Function Selection = Auxiliary Frequency Reference 1]. Set H3-05 = 1 [Terminal A3 Signal Level Select = -10 to +10V (Bipolar Reference)]. 3 Signal type of analog input Set DIP switches S1-1 and S1-3 on the control circuit board to the V-side (voltage). Note: Set this before you energize the drive. 4 Reference 3 Set the value of d1-03 [Reference 3]. 5 Reference 4 Set the value of d1-04 [Reference 4]. 6 Reference 5 Set the value of d1-05 [Reference 5]. 7 Jog Reference Set d1-17 [Jog Reference] to the jog speed. 8 External digital input (3 inputs) Set the Multi-Step Speed Reference 1 to 3 [H1-xx = 3, 4, 5] to one of the MFDI terminals S1 to S8. 9 JOG command Set the Jog Reference Selection [H1-xx = 6] to one of the MFDI terminals S1 to S8. Use the Maximum 17-Step Speed with All Digital Inputs This section is the procedure to set the 17-step speeds (17 types of frequency references) without an analog input. Procedure Configuration Parameter Task Contents 1 Reference 1 Set b1-01 = 0 [Frequency Reference Selection 1 = Keypad]. Set the value of d1-01 [Reference 1]. 2 Reference 2 Set H3-06 = F [Terminal A3 Function Selection = Not Used], and disables the analog reference. Set the value of d1-02 [Reference 2]. 3 Reference 3 Set H3-10 = F [Terminal A2 Function Selection = Not Used], and disables the analog reference. Set the value of d1-03 [Reference 3]. 4 Reference 4 Set the value of d1-04 [Reference 4]. 5 Reference 5 to 16 Sets the values of d1-05 to d1-16 [Reference 5 to 16]. 6 Jog Reference Set d1-17 [Jog Reference] to the jog speed. 7 External digital input (4 inputs) Set Multi-Step Speed Reference 1 to 4 [H1-xx = 3, 4, 5, 32] to one of the MFDI terminals S1 to S8. 8 JOG command Set the Jog Reference Selection [H1-xx = 6] to one of the MFDI terminals S1 to S8. Multi-step Speed Operation Combinations Refer to Table 1 and Figure 1 for information about multi-step speed reference combinations. The selected frequency reference changes when the combination of digital input signals from an external source changes. Table 1.
