234 YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
Note:
• The Jog Frequency Reference (JOG command) overrides all other frequency references.
• You can use the MFDI to switch the frequency reference when the motor is running. The drive will apply the enabled acceleration and
deceleration times.
• The default settings for Multi-Step Speed Reference 1 (master frequency reference) and Multi-Step Speed Reference 2 (auxiliary frequency
reference) are the analog frequency reference.
Also, voltage command input terminal A1 and current input terminal A2 for Multi-Step Speed Reference 1 (master frequency reference) are
added internally by default. The drive uses Multi-Step Speed Reference 1 when the signal is connected to an analog input terminal.
â– Setting Procedures for Multi-step Speed Operation
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 A2 to 0 V to 10 V (Lower Limit at 0)
Procedure Configuration Parameter Task Contents
1 Reference 1 1. Set b1-01 = 1 [Frequency Reference Selection 1 = Analog Input].
2. Set H3-02 = 0 [Terminal A1 Function Selection = Frequency Reference].
3. Set H3-01 = 0 [Terminal A1 Signal Level Select = 0 to 10 V (Lower Limit at 0)].
2 Reference 2 1. Set H3-10 = 2 [Terminal A2 Function Selection = Auxiliary Frequency Reference 1].
2. Set H3-09 = 0 [Terminal A2 Signal Level Select = 0 to 10 V (Lower Limit at 0)].
3 Signal type of analog input Set Jumper switch S1 on the control circuit board to the V-side (voltage) to set terminal A2 for voltage input.
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 S7.
9 JOG command Set the Jog Reference Selection [H1-xx = 6] to one of the MFDI terminals S1 to S7.
Use the Maximum 9-Step Speed with All Digital Inputs
This section is the procedure to set the 9-step speeds (9 types of frequency references) without an analog input.
Procedure Configuration Parameter Task Contents
1 Reference 1 1. Set b1-01 = 0 [Frequency Reference Selection 1 = Keypad].
2. Set the value of d1-01 [Reference 1].
2 Reference 2 Set the value of d1-02 [Reference 2].
3 Reference 3 1. Set H3-10 = F [Terminal A2 Function Selection = Not Used], and disables the analog reference.
2. Set the value of d1-03 [Reference 3].
4 Reference 4 to 8 Set the values of d1-04 to d1-08 [Reference 4 to 8].
5 Jog Reference Set d1-17 [Jog Reference] to the jog speed.
6 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 S7.
7 JOG command Set the Jog Reference Selection [H1-xx = 6] to one of the MFDI terminals S1 to S7.
Multi-step Speed Operation Combinations
Refer to Table 5.32 and Figure 5.33 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.
