BMU Series, Clarifications

Post by Mr.Thota » Mon Jul 15, 2019 7:04 pm

Hi !!
Good Day !!

Requested to please ignore our previous post which is on 13th July, and requested to please consider below mail as on priority and orgnize the reply at the earliest.

We are planning to use BMU Series for one of Conveyor Application, wherein we required to control Forward & Reverse directions through our PLC, indeed we required the clarifications for the following:

1. Please provide us MCB rating (Circuit Breaking) for BMU 30 Watts & 120 Watts (BLM460S-30B + BMUD60-C2 and BLM5120HPK-5H30S + BMUD120-C2) ??
2. Regarding the I/O signals, we want to use forward (X0) & reverse (X1) terminals only, whether it is mandatory to use terminal X2 also ??
3. What is the X2 terminal ?? which signal is used to select the operation data ?? without using this how it would be ??
4. What is the use of X2 terminal and whether shall we use without X2 Also. We are plan to use only X0 , X1 .
5. We may will take the output in future ( Whether is this like Digital output) ??
6. What is the Current Consumption at 100 rpm 3.5 N-m for both models (We know 60 Watts Rated Current is 1 Amps,230 V Ac ; 120 watts Rated Current is 2 Amps , 230 V Ac ) as above said models.

Requested to please clarify the above, as we need to be take further decision in this regard.

Thanking you and Best Regards,

Hi Mr.Thota,

The circuit breaker we recommend is the Mitsubishi Electric Corporation NF30. This is referenced on page 12 of the manual I will link below.

https://www.orientalmotor.com/products/ ... 187-4E.pdf

The X2 terminal is not mandatory to use. You would only need to use this if you have more than 1 speed programmed. When turning on the forward and reverse inputs you will run the speed set in data 0. If you want to run the speed set in data 1 then you will have to use the X2 terminal which is the M0 input.

For the outputs they are open collector type so you will have to supply a voltage 4.5 to 30 VDC, 100 mA or less. Use resistors to limit current. You can reference a sample wiring diagram on page 16.

For the current draw at this speed and torque it would be around 0.2 A for both motor driver combinations.

Hi !!
Good Day !!

Thankyou verymuch for your details, as you know, the recommended mcb is not clear view, NF30 Means that is one of the Series that is it. In that Manual ,they are give 10 Amps Circuit Breaker for 230 V Ac 1 Ph +N , 5 Amps Circuit Breaker for 230 V Ac 3Phase . Then shall use 2 P ,10 Amps Circuit Breaker for the BMU Series Controller. But our max current itself below 2 amps for two model and 4.1 max current for hollow shaft model. Kindly review the same and provide us the Exact clear details. Here again we placed queries .Kindly provide the details against that quires .

Required Details:

1.What is the Recommended MCB for Both Model - ??? Required Details
2.What is the Current Consumption at 100 rpm 3.5 N-m for both model ( We know 60 Watts Rated Current is 1 Amps,230 V Ac ; 120 watts Rated Current is 2 Amps , 230 V Ac ) - ??? Required Details
3.Can we use this 3 model Just Indoor Application . ( Like titan Shop Floor without any Enlosure) - ??? Required Details
4.Confirm the Compatibility for Geraman. Share the German Support team details for future contacting purpose.- ??? Required Details
5.What is the use of X2 terminal and whether shall we use without X2 Also. We are plan to use only X0 , X1 . - ??? Required Details
6. We are planning to use variable speed and forward & reverse directions from PLC operation and le tus know the compeatablity to proceed further in this regard.
7.We may will take the output in future .( Whether is this like Digital output).- ??? Required Details

Requested to please clarify the above point to point and as we need to be submit this details to END user.

Please look into this and do the favourabel support.

Hi Mr.Thota,

1. Higher rated current circuit breakers are recommended because of inrush current at start up and when you start running the motor the current draw would be the max current spec given. You can use other circuit breakers that are closer to the max current draw but make sure they are slow blow type so they won't be tripped by the inrush current at start up.

2. For the current draw at this speed and torque it would be around 0.2 A for both motor driver combinations. This is reference value can vary.

3. Yes we only recommend using these products for indoor applications. The motor is IP66 rated and driver is IP20 rated. Below are the IP ratings for you reference.

4. This is the contact information for our Germany office.

5. X2 terminal is factory set to M0. With this input you choose between the speeds set as data 0 and data 1. When off it chooses data 0 when on it chooses data 1. This is not necessary if only using speed set on data 0 or if using dial to change speed.

6. You can change the speed with dial when you set parameter External operation signal input from off to on. You can change direction with the X0 and X1 inputs. If you set the External operation signal input parameter to rE then it disables the front dial and run off speeds programmed in the driver. Reference page 26 in the manual.

7. For the outputs they are open collector type so you will have to supply a voltage 4.5 to 30 VDC, 100 mA or less. Use resistors to limit current. You can reference a sample wiring diagram on page 16.
