1 : Zero Speed Holding
When the output frequency falls below the d1-08 (Minimum Output Frequency) or b2-00
(Zero Speed Holding Start Level) setting, the output terminal closes.

Description
Open
Output frequency is higher than the d1-08 or b2-00 setting
Closed
Output frequency is lower than the d1-08 or b2-00 setting
Note: In IM/ PM Closed-Loop Vector Control, the terminal closes when the output frequency falls below the b2-00
setting. In all other control method, the terminal closes when the output frequency falls below the d1-08 setting.

2 : Frequency (Speed) Agree
When the output frequency is within the value set to ±P4-01 (Frequency Detection Width), the
output terminal closes regardless the rotation direction.
Terminal
Description
Open
The output frequency does not match the frequency demand during run
Closed
Output frequency is within the value set to ±P4-01
Note:
1. The detection works in both forward and reverse directions.
2. In Closed-Loop Vector Control, the terminal closes when the motor speed is within the value set to P4-01.
