AC70-T Synchronous control function
  • AC70-T Synchronous control function

AC70-T Synchronous control function

Automatic speed increment when light load or empty hook, matching optimal operating speed
Zero-speed torque retention prevents the brake from slipping due to long mechanical delays
Synchronous control function ensures that two hoisting mechanisms are synchronized to ensure safety
Anti-collision function to prevent collision
AC70-T Series Lifting Dedicated Frequency Inventer

1. Master-slave speed synchronization control function: When the double hoisting mechanism lifts a heavy object at the same time, then it can ensure that two hoisting mechanisms are synchronously promoted to ensure safety

2. Real-time correction control (closed-loop mode): It is suitable for applications with large spans. The master-slave adopts real-time position correction to meet the synchronous control of the position of the cart (applicable to driving and traveling equipment of gantry crane)
