Accommodating various applications
z
Convenient functions for operations at the specified speed
Pulse train input speed command supported as standard
The FRENIC-MEGA can issue a speed command with the pulse train input (single-phase pulse train with
sign). (Maximum pulse input: 100 kHz)
Ratio operation
The ratio operation is convenient for synchronous control of two or more carrier machines in a multiline
conveyor system. It is possible to specify the ratio of the main speed to other follower motors as a
frequency command, so the conveying speed of carrier machines that handle variable loads or loading
situations can be synchronously adjusted easily.
Analog input (Ratio setting)
Frequency command output = Frequency command input ×
100%
z
Customized logic interface function on the inverter
By setting parameters, logic inputs and outputs can be easily created, enabling easier peripheral circuits.
Logic circuits: AND, OR, XOR, flipflop,
leading or trailing edge detection, counter, etc.
General-purpose timer: On-delay, off-delay, pulse train, etc.
Time setting: 0.0 to 600 sec.
Output signal: Input/output of inverter control,
Input of customized logic
Can be combined up to 10 steps
