4-2 Function Mode UP/DOWN Function This function changes the Inverter output frequency using the multi-function input. 4 Functions •While the UP/DWN terminal is turned on, the acceleration/deceleration time depends on F002, F003/F202, and F023. To switch to the 2nd control, allocate 08 (SET) to the multi-function input and then turn on/off the SET terminal. •You can store a frequency set value after UP/DWN adjustment. Choose whether to store the value with C101. Also, you can clear the stored frequency set value by allocating 29 (UDC) to the desired multi- function input and turning on/off the UDC terminal.
UP/DOWN Function Enabled/Disabled •The UP/DOWN function is disabled when the JG operation (06) is enabled. •The UP/DOWN function is enabled when the frequency reference selection (A001) is set to the Digital Operator (02). •The UP/DOWN function is enabled when the multi-step speed reference is enabled. 4-50 Data Symbol Function name Status Description 27 UP UP/DWN function accelerated ON Increases the current speed during the signal input period. OFF Keeps the current speed. 28 DWN UP/DWN function decelerated ON Decreases the current speed during the signal input period. OFF Keeps the current speed. 29 UDC UP/DWN function data clear ON Clears the stored UP/DWN speed.
OFF Keeps the stored UP/DWN speed. Available input terminals C001, C002, C003, C004, C005, C006 Required settings A001 = 02, C101 Frequency reference selection (A001) Multi-step speed Jogging Enabled/ Disabled ON Disabled ON OFF Enabled 00 OFF OFF Disabled 01 OFF OFF Disabled 02 OFF OFF Enabled 03 OFF OFF Disabled Parameter No. Function name Data Description C101 UP/DWN selection 00 Does not store the frequency reference adjusted using UP/DWN. After restoring the power, returns to the value set before UP/DWN adjustment. 01 Stores the frequency reference adjusted using UP/DWN. After restoring the power, maintains the set value after UP/DWN adjustment.
