Reverse Rotation Prevention Selection; Frequency Setting Via Pulse Train Input - Mitsubishi Electric 800 Series Instruction Manual

(D) Operation command and frequency command
5.9.4

Reverse rotation prevention selection

This function can prevent reverse rotation fault resulting from the incorrect input of the start signal.
Pr.
78 Reverse rotation prevention
D020 selection
• Set this parameter to limit the motor rotation to only one direction.
• This parameter is valid for all of the reverse rotation and forward rotation keys of the operation panel and of the parameter
unit, the start signals (STF, STR signals) via external terminals, and the forward and reverse rotation commands through
communication.
5.9.5

Frequency setting via pulse train input

A pulse train input to the terminal JOG can be used to set the inverter's speed command.
Moreover, speed synchronized operation of an inverter can be performed by using the pulse train output together with
the terminal JOG.

Division ratio on the input pulse. The frequency resolution on
1 to 250
the input pulse changes according to this setting.
0 to 590 Hz Sets the frequency when the input pulse is zero (bias).
0 to 590 Hz Sets the frequency when the input pulse is maximum (gain).
