Start signal operation selection
Operation of start signal (STF/STR) can be selected.
Select the stopping method (deceleration to stop or casting) at turn-OFF of the start signal.
Use this function to stop a motor with a mechanical brake at turn-OFF of the start signal.
2-wire type (STF, STR signal)
●
The following figure shows the connection in 2-wire type.
●
As an initial setting, forward/reverse rotation signals (STF/STR) acts as both start and stop signals.
Either one turned ON will be enabled, and the operation will follow that signal. The motor will
perform a deceleration stop when both are turned OFF (or both are turned ON) during the
operation.
●
There are methods such as inputting 0 to 10 V DC between the speed setting input terminals 2
and 5, or Pr. 4 to Pr. 6 (multi-speed setting (fast, medium, slow)) for the frequency setting signal.
(For multi-speed operation, refer to page 5-189.)
●
By setting Pr. 250 = "1000 to 1100, 8888", STF signal becomes start command and STF signal
becomes forward/reverse command.
