1. Use the operation method of clicking the button:
In addition to the direction of travel, 2 logic inputs are required to add a speed given, e.g. LI5 is assigned the acceleration function, and LI6 is assigned the deceleration function. Then pressing LI5 will add the given velocity, and pressing LI6 will decrease the given velocity.
2. Use the operation method of double-clicking the button:
Only one logical input is required to be assigned to "+speed", e.g. LI5. Use the double-click button to add and detract the speed, take the forward direction as an example, when LI1 is closed, after the Schonei inverter is running, then turn on the "+ speed", for example, LI5, the speed will be added when the speed is given, after disconnecting LI5, insist that LI1 is turned on, and the speed value will be adhered to. If LI1 is disconnected for a period of time and then turned on, the given value of the speed and the practical speed will also decrease.

Schneider power supply configuration UPS backup battery method
In order to ensure that the APCUPS power supply can continue to provide high-quality power to the computer in the event of a power outage, it is particularly important to equip the battery backup battery. When the frequency load does not agree to be supplied with power, the backup time of the UPS battery in the communication room should be greater than the time from the suspension of the mains power to the recovery or until the generator set is normal.
