Product Description:

The MIV15-3-V5 Servo Drive powered by Okuma serves as a product for accurate control applications of Industrial automation. Stable motor operations occur in this drive due to its maintained voltage range from -3 V to +3 V. The system offers a motor operational capacity of up to 15 kW (20 hp) to serve high-performance functions.

An efficient speed control function exists in MIV15-3-V5 Servo Drive because the first-axis motor operates at 1562 min⁻¹/V frequency. The motor output torque for the first-axis reaches its peak performance at 3 V which enables effective torque control. The maximum output torque of the second-axis motor becomes accessible through a 3 V input. Within the A-phase signal of the magnetic encoder it maintains a voltage span from 2.6 V to 4.6 V. Correct adjustment of the gap produces a 3.3 V signal which guarantees steady feedback. Position sensing in MIV15-3-V5 Servo Drive operates reliably because the B-phase signal maintains its operations between the same voltage range. Z-phase signals deliver mobile motor accuracy by providing 1.4 V minimum Vz1 along with 0.5 V minimum Vz2. The d-axis voltage error has an output relationship factor that equals 1/42. These voltage errors in both the q-axis are controlled using 1/42 multiplication factors for maintaining motor precision.

A power regeneration system is integrated into the MIV15-3-V5 Servo Drive. Two voltage outputs from this system operate as 300 VDC and 24 VDC to guarantee safe operation and effective power recovery. The device uses alarm codes to detect +5 V and +12 V power supply errors thus improving fault identification. A resolver signal generates 6.0 V while responding at 0.128 milliseconds for 7.81 kHz operation. External dimensions fit different configurations which enables manufacturers to build compact installations with this unit.
