No. (Hex.) Name Description Default (Range) b3-14 (019E) Bi-directional Speed Search Sets the direction of Speed Search to the direction of the frequency reference or in the motor rotation direction as detected by the drive. Determined by A1-02, b3-24, and E9-01 (0, 1) Note: The initial value of b3-14 [Bi-directional Speed Search] is different for different A1-02 [Control Method Selection] settings when you set these parameters: Refer to Parameters that Change from the Default Settings with A1-02 [Control Method Selection] for information. A1-02 = 0, 2, 8 [V/f, OLV, EZOLV] E9-01 = 0 [Motor Type Selection = Induction (IM)] b3-24 = 1 [Speed Search Method Selection = Speed Estimation]. The initial value of b3-14 is 0 when you set these parameters: A1-02 = 0, 2, 8 E9-01 = 0 b3-24 = 2 [Current Detection 2] The initial value of b3-14 is different for different A1-02 settings when you set these parameters: Refer to Parameters that Change from the Default Settings with A1-02 [Control Method Selection] for information. A1-02 = 1, 4, 8 [CL-V/f, AOLV, EZOLV] E9-01 = 1, 2 [Permanent Magnet (PM), Synchronous Reluctance (SynRM)] When you set A1-02, b3-24, and E9-01, set b3-14. 0 Disabled The drive uses the frequency reference to detect the direction of motor rotation. 1 Enabled The drive detects the direction of motor rotation during Speed Search.
