Oiltech Controls’s Insight

• This drive excels in retrofitting obsolete drives – it supports both asynchronous and synchronous motors.
• We recommend using shielded cable up to 50 m; for longer runs use an output filter.
• For hoisting applications, add an external braking resistor to utilise the 150 % braking torque.
• Set the switching frequency ≤4 kHz to avoid derating in high‑ambient conditions.
• Use the adjustable PI regulator for closed‑loop pressure or flow control.

Frequently Asked Questions (FAQ)

• Q: What is the maximum motor cable length without a filter?
  A: 50 m shielded, 100 m unshielded. For longer runs, use an output reactor.
• Q: Can this drive run a permanent magnet synchronous motor?
  A: Yes. It supports synchronous motor control via vector control without speed feedback.
• Q: How to choose between open‑loop and closed‑loop?
  A: Open‑loop (SFVC) suits general speed control. Closed‑loop (FVC) with encoder gives ±0.01 % speed accuracy.
• Q: Does the drive include a braking resistor?
  A: No. Braking resistor is optional. Without it, braking torque is 30 %.
• Q: What communication protocols are supported natively?
  A: Modbus RTU and CANopen. Additional fieldbus cards are optional.
