Mitsubishi Electric FX2N-1HC User Manual

This manual contains text, diagrams and explanations which will guide the reader in the correct installation
and operation of the FX -1HC special function block and should be read and understood before attempting
2N
to install or use the unit.
Further information can be found in the FX PROGRAMMING MANUAL and FX
MANUAL.
1. INTRODUCTION
• The hardware high-speed counter block is a 2-phase 50 kHz high-speed counter. It is a special function
block for the FX , FX series PLC. The FX
2NC
2N
speed counter of the PLC (2-phase 30 kHz, 1-phase 60 kHz) and performs comparisons and outputs
directly.
• Various counter modes, such as 1-phase or 2-phase, 16-bit or 32-bit modes, can be selected using
commands from the PLC. Allow the FX
• The source of your input signal should be a 1 or 2 phase encoder. A 5V, 12V, or 24V power source can
be used. An initial value setting command input (PRESET) and a count prohibit command input (DIS-
ABLE) are also available.
• The FX -1HC has two outputs. When the counter value coincides with an output compare value, the
2N
appropriate output is set ON. The output transistors are individually isolated to allow either sink or
source connection methods.
• Data transfer between the FX
buffer memories (each of 16 bits) in the FX
• The FX -1HC occupies 8 points of I/O on the FX
2N
cated from either inputs or outputs.

• Use crimp terminals of the dimensions specified in the left figure.
• Secure the terminals using a tightening torque of 0.5 to 0.8 Nxm
(5 to 8 kgxcm).
• Wire only to the module terminals discussed in this manual.
Leave all others vacant.
