3 Operation Procedure for Drive Programming
3 - 16
Drive Programming User’s Manual (I580-E2)
When the Drive Programming function is started/stopped through the CX-Drive, the value of the
inverter parameter, Drive Programming Function Selection (A017) is temporarily changed to 02
(start) or 00 (stop) only in the RAM data.
Take the following measures after you started/stopped the Drive Programming function through
the CX-Drive.
• Turn ON the power supply for the inverter again and return the value of A017 to that saved in
the EEPROM.
• Do not perform the following EEPROM saving operations before you turn ON the power sup-
ply for the inverter.
• Transferring (downloading) a part of parameters from the CX-Drive.
• Issuing the “enter” command via the Modbus communication or a communication option.
When the Drive Programming program is started, five tasks are started simultaneously.
If you create a loop construction in a task by using commands such as the “goto”, the task will repeat
the loop after it is started.
When the Drive Programming program is stopped, five tasks are stopped simultaneously.
If the program is stopped while the Motor is running, the Motor will be stopped according to the setting
for the Stop Selection (b091) (deceleration stop or free-run stop).
The task operations for different settings are shown below.
