Kinco JD2 Series AC Servo Drives replacement and alternative options
Use these supply-network options as a starting point for an engineering check. We can also help source the original Kinco part. Published series figures do not establish an exact-model or drop-in replacement: confirm ratings, fit, interfaces and approvals for your application.

Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.

Typical applications
What an AC servo drive is
An AC servo drive, or servo amplifier, powers and controls a servo motor from mains supply. It rectifies the AC input to a DC bus, then uses an inverter of power transistors switched by PWM to produce controlled three-phase current in the motor. Nested current, velocity and position loops use encoder feedback to follow commands from pulse and direction, analogue or industrial Ethernet. Modern drives add auto-tuning, vibration suppression and safety functions such as safe torque off.
When engineers choose an AC servo drive
Choose an AC servo drive for mains-powered machines with servo axes from tens of watts to many kilowatts, such as packaging, machine tools and robotics. It gives precise, dynamic control with standard industrial interfaces. The trade-offs are cabinet space, wiring, EMC measures and the need to match motor and feedback. For low-voltage or mobile machines, a DC drive is more suitable; for many axes in one cabinet, a multi-axis drive may save space.
How to specify the Kinco JD2 Series AC Servo Drives
Send these with your enquiry and an engineer can confirm the right JD2 Series AC Servo Drives variant:
- Supply voltage and phases (V AC)
- Continuous and peak output current (A rms)
- Motor and feedback compatibility
- Command interface: pulse, analogue, EtherCAT, PROFINET and so on
- Safety functions, such as STO, and their rating (SIL, PL)
- Braking resistor and regenerative energy (W, J)
- Ambient temperature, mounting and cooling
Common mistakes to avoid
- Sizing on motor rated current without the drive's peak duration
- Ignoring regenerative energy on fast decelerations or vertical axes
- Leaving out EMC filtering and screened motor cables
- Mixing motor and encoder types the drive does not support
Kinco JD2 Series AC Servo Drives: frequently asked questions
Can you help replace Kinco JD2 Series AC Servo Drives or source the original?
Send the full model code, quantity and required date. Our engineers can check original-part availability and assess suitable alternatives, including supply-network options where appropriate. We confirm compatibility and any changes needed before recommending a replacement.
What is the Kinco JD2 Series AC Servo Drives?
The second-generation Kinco JD drive, paired with SMK motors from 50 W to 7.5 kW. It accepts a very wide range of encoder protocols plus a second encoder, runs CANopen or EtherCAT, and has STO SIL3 / PL e on every model. Published series figures include power 50 W, power 7,500 W, axes 1, continuous current 26 A. It is available through our supply network, and our engineers can confirm the right variant for your application.
Who makes the Kinco JD2 Series AC Servo Drives?
The Kinco JD2 Series AC Servo Drives is made by Kinco (Kinco Automation) available through our supply network. Send us your requirement for pricing, lead time, datasheets and CAD.
What is the power of the Kinco JD2 Series AC Servo Drives?
The published series minimum power is 50 W. Individual models and sizes in the JD2 Series AC Servo Drives range vary, so check the exact variant against your duty cycle, mounting and environment, or ask our engineers to confirm the right size for you.
Is there an alternative to the Kinco JD2 Series AC Servo Drives?
We can assess suitable replacement options. On published figures, Leadshine EL7S / EL7 Series AC Servo Drives and ADVANCED Motion Controls DigiFlex Performance Servo Drives (DP, DZ, DV) are options to assess from our supply network. An engineer confirms the fit against your application before recommending anything.
Does a servo drive need a braking resistor?
When a servo motor decelerates, it acts as a generator and returns energy to the drive's DC bus. If the bus capacitors cannot absorb it, the voltage rises and the drive trips. A braking resistor dissipates the energy as heat. Fast decelerations, high inertia and vertical axes usually need one.
What is safe torque off on a servo drive?
Safe torque off, or STO, is a safety function that removes power that could produce torque at the motor, without disconnecting the drive supply. It is defined in IEC 61800-5-2 and used as part of a machine's safety system. Check the safety level achieved and wiring requirements.
