Source text - English Adding a run confirm delay time in the PLC program would help in instances where the relay momentarily opens or delays in closing. However, this will not remedy cases where the relay does not close at all (such as observed on Line 20).
ﾊ
It would be beneficial to replace the Weigh Feed Conveyor drive on Line 20 with a drive that incorporates the improved relay, a relay that has higher vibration tolerance and a higher mechanical life expectancy, so that:
ﾊ
a. A drive with a known intermittent relay can be analyzed at Yaskawa.
b. Testing can begin with the improved relay to determine its effectiveness in withstanding the actual environment.
ﾊ
The output relay is being used as a ﾒrun confirmﾓ signal at a rate of approximately 5 cycles/minute. The high cycle rate (approx. 200,000 cycles per month) along with the low current passing through the relay contacts (approx. 8 mA) makes the solid state photo-coupler output attractive as an alternate method. The photo-coupler will not exhibit wear and is perfectly suitable to pass low current (50mA maximum). However, the input card within the PLC would need to be changed to a sourcing type. This also means closer scrutiny will be required by the designers of the system to insure compatibility between the drive and PLC for the voltage being used. Some users require 120Vac for feedback. The photo-coupler solution is compatible with 24 or 48Vdc inputs only.
Translation - Japanese PLCプログラムの「run confirm」に遅延時間を加えれば、リレー接続に延滞が生じる問題の多くは改善すると思われます。しかし、その措置でも（20番ラインの一部でみられるような）リレーが全く接続しないというケースを解決することは出来ません。
従ってより望ましい措置としては、20番ラインの計量フィードコンベアの駆動機構を振動トレランスがより高く機械寿命のより長いリレーを新たに組み込んだ駆動機構に取り替えることであり、その為に下記２点を行うことでａB
a. 当該の断続症状があると確認されたリレーがついている駆動機構をYaskawa にて分析すること。
b．テストは、改良されたリレーを最初に用いて実施し、現場での使用環境に有効であることを確認すること。
ﾊ
出力リレーは「run confirm」シグナルとして毎分約５サイクルの頻度で使用されています。この高いサイクルレート（月毎約20万サイクル）とリレー接点を通る低電流（約 8mA ）の条件下では、ソリッドステートのフォトカプラ出力が代替として有効です。フォトカプラは摩耗が生じず、当該の低電流（最大50mA）を通すには最適です。但し、PLC 内の入力カードはソースタイプに変える必要があるでしょう。その為には、駆動機構・ PLC 間の使用電圧の互換性を確保するために、当該システムの設計者は更に精査することが必要となります。ユーザの数社ではフィードバックのために120Vacが使用されていますが、上記フォトカプラによる解決策で互換可能なのは、24 または48Vdc入力だけです。

Source text - English This module demonstrates the use of the XXXXXXXXX series by guiding you through a three-step trial operation process.
Trial Servomotor Operation Without Load, Under Jog Control
Trial Servomotor Operation Without Load, Under Host Control
Trial Servomotor Operation With Load, Under Host Control
Understand the XXXXXXXXX product designation.
Execute jog motion.
The first step in setting up your XXXXXXXXX series product is to ready the XXXXXXXXX and servomotor for testing in jog mode.
To do so, you will follow the process below:
Confirm the designation of your product.
Confirm Product Designation
Introduction to XXXXXXXXX Designations
The model name or designation of each servomotor or XXXXXXXXX is displayed on the product nameplate.
The motor is fitted with a 17-bit incremental serial encoder.
The motor shaft end is straight, without key.
The motor has no options fitted.
The motor is fitted with a 90-VDC brake.
Take necessary precautions when water drops or water or oil mist are present.
Cable Stress:
Align and couple the shafts of the servomotor and the equipment.
The alignment accuracy specifications are shown in the Viewer.
Always observe the following precautions for installation.
