11.8 H: Terminal Functions
712 YASKAWA SIEPC71061723A YASKAWA AC Drive CR700 Technical Manual
Figure 11.59 Drive Running Time Chart
ON : Drive is during run
The Run command is input or the drive is in deceleration or DC injection.
OFF : Drive is stopped
■ 1: Zero Speed
Setting Value Function Description
1 Zero Speed
The terminal activates when the output frequency is less than E1-09 [Minimum Output Frequency] or b2-01 [DC Injection/Zero
SpeedThreshold].
Note:
The parameter used as the reference is determined by the setting of A1-02 [Control Method Selection].
A1-02 Settings Description Parameter Used as the Reference
0 V/f Control E1-09
1 Closed Loop V/f Control E1-09
2 Open Loop Vector Control b2-01
3 Closed Loop Vector Control E1-09
4 Advanced Open Loop Vector Control E1-09
Figure 11.60 Zero Speed Time Chart
ON : The output frequency is less than the value of E1-09 or b2-01.
OFF : The output frequency is the value of E1-09 or more, or b2-01 or more.
■ 2: Speed Agree 1
Setting Value Function Description
2 Speed Agree 1
The terminal deactivates when the output frequency is in the range of the frequency reference ± L4-02 [Speed Agree Detection
Width].
Note:
• The detection function operates in the two motor rotation directions.
• The drive outputs the motor speed status when A1-02 = 3 [Control Method Selection = CLV]. The drive outputs the motor speed status
when A1-02 = 4 [Control Method Selection = AOLV] and n4-72 = 1 [Speed Feedback Mode = With Encoder].
