To avoid improper brake operation make sure that frequency detection is set so thatthe brake does not open during Baseblock (L4-07 = “0”, default).Brake Open/Close Brake Activation LevelFunction Parameter Signal ParameterFrequencyDetectionConditions L4-07 = 0 Frequency Detection Level L4-01 = 2.0 to 3.0 Hz <1>FrequencyDetection 2 H2-01 = 5 Frequency Detection Width 2.0 Hz (fixed)<1> If the load slips during stop, make it greater than E1-09 or 2.0 Hz until the load no longer slips.2.0 Hz (fixed)L4-01OFFONTimeOutputFrequencyFrequencyDectection 2Figure 5.86 Frequency Detection 2The braking sequence should be designed as follows:• A normally open signal (N.O.) should be used to control the brake so that it is released when terminal MA-MC closes.5.8 L: Protection Functions218 YASKAWA ELECTRIC SIEP C710606 16C YASKAWA AC Drive – V1000 Technical Manual
