4-2 Function Mode „ Jogging Frequency •If the frequency is set to a higher value, the jogging operation may easily lead to a trip. Adjust A038 so that the Inverter does not trip. 4 „ Jogging Stop Selection Note 1: To perform the jogging operation, turn on the JG terminal before the FW or RV terminal. (Do the same if the RUN command source is set to the Digital Operator.) Functions JG FW Output frequency Jogging does not function if the FW signal turns on beforehand. Note 2: If A039 is set to 02, set the DC injection braking. External DC Injection Braking This function securely stops the motor rotation as the motor decelerates to a stop.
For internal DC injection braking, refer to "DC Injection Braking (DB)" (page 4-15). •If DC injection braking is applied at a high motor speed, an overcurrent trip (E01 to E04) or overload trip (E05) may occur. For internal DC injection braking, the following adjustment may help you avoid such a situation: Lower the frequency for DC injection braking. Increase the DC injection braking delay time (A053). •Allocate 07 (DB) to the desired multi-function input. DC injection braking can be applied by turning on/off the DB terminal, regardless of the DC injection braking selection (A051). •Set the DC injection braking power in A054.
•Set the DC injection braking time, taking into account motor heat generation. Long continuous DB may cause the motor to burn out. 4-49 39 = 01) JG FW RV Output frequency A038 Data Symbol Function name Status Description 07 DB External DC injection braking ON DC injection braking is performed during deceleration.
