Product Description

The introduction of the BL class of brushless servo motors from Okuma was significant, as they performed excellently across all their industrial applications and were very maintainable. However, in order to keep up with newer trends and performance benchmarks within the automation industry: especially with an increasing demand for higher precision in servomotors, Okuma designed the type-A BL-D series of servo drives to maximize the performance range of the brushless BL motors. The BL-D75A is a variant of the type-A BL-D series of servo-drives, which is optimized for servomotor with medium output power requirements.

For the BL-D75A, the value ‘75’ in its name indicates its power unit capacity. This is proportional to its output power range, along with its capacity for producing and amplifying the required current signals for the connected servomotor. There are a few BL-type servomotors that fall within this power range, and they include the following: BL-MQ120E-20, BL-MH151E-20, BL-MS125E-20, BL-MS125E-30, BL-MQ180E-20, BL-MQ120E-30, BL-MS140E-30, BL-MU180E-20, BL-MH201E-20, BL-MH301E-20, BL-MH301E-12, BL-MH401E-12, BL-MH201E-30. Since this servo-drive is a single-axis unit, it can only be connected to one servomotor at a time. Basically, while incorporated within the multi-axis control CNC BDU-A unit, up to six BL-D**A servo amplifiers can be connected to the same DC source at a time. This can easily increase throughput in automation, however, with only one compatible motor connected to a servo-amplifier per time.

This servo-drive uses a pulse modulation technique for regulating speed and torque outputs in servomotors. While the recommended operating conditions with regards, input electrical parameters like voltage and frequency are meant to be applied at all instances of operating this drive, it comes with extra circuitry for protecting the servomotor from common electrical damages and faults. This further extends the reliability of an already optimized product (BL servomotors) from Okuma.

Frequently Asked Questions about BL-D75A


Q: What type of electrical motor is the BL-D75A designed for?

A: The BL-D75A servo motor is designed to control the speed, position and general operation of the BL servo motor. The

Q: How can the operational status of the BL-D75A be monitored in real time?

A: The BL-D75A servo amplifier displays operational status through special light emitting diodes. The In the case of malfunction, the alarm message is displayed on the NC operation panel and a corresponding status indicating diode is lit.

Q: Is the BL-D75A still in production by Okuma?

A: This servo drive have been discontinued by okuma. However we still offer a 1year warraty protection for customers that purchase the device from our store.

Q: What instruments do operators need for the proper maintenance of the BL-D75A?

A: The maintenance of the BL-D75A is a simple process that requires an AC voltmeter, and analog circuit tester and a philips screwdriver. Maintenance operations should only be carried out by industrial professionals.

Q: How long will it take wake industrial to complete the repair of a faulty BL-D75A?

A: Generally devices sent to us for repair are examined and repaired within 10 days. Our certified engineers will make sure your servo amplifier is as good as new.
