Simple Manual
Small Sized Frequency Variable Controller
High Function Type
K-ECG25 (Control capacity 2A)
K-ECJ45 (Control capacity 4.5A)
Introduction
Thank you for your purchase of NTN small sized frequency variable controller (High function type). For correct and
safe operation of the controller, please read without fail ‘Precautions for safety’ in the separate operation manual
carefully before use.
１．Vibration sensor K-P1398 (Refer to P. 13 of operation manual)
＜Installation direction of vibration sensor＞
As the vibration direction of sensor is predetermined (Arrow mark printed on
sensor is the travel direction of work), please note the installation direction.
When it is not possible to match the direction of arrow mark to the forwarding
direction of work, please install it in the reverse direction and reverse the polarity
with the function J07.
Note) There is a case that it become to reverse direction depending on
vibrator.
２．Outside view (Refer to P59 of operation manual for size) ３．Reference diagram of wiring (Refer to p9 and after of operation manual)
The following diagram is explained about K-ECF25. But
the layout of parts is same with K-ECH45.
＊１ 配線工事・各種調整等に際しては取扱説明書を必ず読んでください。間違えると故障・
事故の可能性があります。
＊２ リモート端子を使用しない場合は、接点の代わりにジャンパ線を接続してください。
＊３ 24Vと0V端子はそれぞれ内部で全て接続されています。
＊４ 電流制限器：入力回路に流れる電流も含めた合計値が200mAに近付くと電圧降下を始めます。

*1 Read the operation manual in doing wiring construction and other various adjustments.
Error may cause failure and accident.
*2 Space between X1-0V terminals are short-circuited at the time of shipment.
When you do not use a remote terminal, connect a jumper wire instead of contact.
*3 Terminals 24V and 0V are all connected in the inside.
*4 Current limiter: When total figure including current in input circuit comes close to 200mA,
voltage starts to drop.
