8118 AUTOCHNG INTERV
Controls operation of the Autochange function and sets the
interval between changes.
• The Autochange time interval only applies to the time when
the speed regulated motor is running.
• See parameter 8119
Autochange function.
• The drive always coasts to a stop when autochange is
performed.
• Autochange enabled requires parameter 8120
value > 0.
0.0 = – Disables the Autochange function.
NOT SEL
0.1...336 = The operating time interval (the time when the start
signal is on) between automatic motor changes.
Warning! When enabled, the Autochange function
requires the interlocks (8120 interlocks = value > 0)
enabled. During autochange the interlocks interrupt the
drive's power output, preventing damage to the
contacts.
