Model Number Breakdown

• CACR: AC Servo Drive (SERVOPACK)

• SR: Speed/position control, VS‑800 platform

• 15: Rated power 1.5 kW

• S: For Yaskawa S‑series servo motors

• Z: Special hardware variant (custom I/O/feedback)

• 1: Single‑phase 200 VAC control power

• S: Serial encoder interface (not incremental)

• D: Custom base firmware

• Y21: OEM‑specific parameter set

Key Specifications

• Main Power: 3‑phase 200–230 VAC, 50/60 Hz

• Control Power: 1‑phase 200–230 VAC

• Output Power: 1.5 kW

• Continuous Current: 9.9 A

• Peak Current: ~28 A

• Feedback: Serial encoder (S‑series compatible)

• Control Modes: Analog speed/torque, pulse position

• Communication: RS‑232C / RS‑485 (Modbus RTU)

• Mounting: Vertical panel

• Temperature: 0°C to +45°C (operating)

• Humidity: ≤80% RH, non‑condensing

• Protection: Overcurrent, overvoltage, undervoltage, overheat, encoder fault, overload (150% / 60 s)

Core Features

• Serial Encoder Support: Higher noise immunity and longer cable runs than incremental types.

• Y21 OEM Tuning: Pre‑configured parameters for target machines, minimal on‑site setup.

• Robust & Compact: Proven VS‑800 hardware, suitable for tight control panels.

• Easy Maintenance: Standard diagnostics and status LEDs simplify troubleshooting.

Differences from CACR‑SR15SB1BF‑Y160

• Feedback: This model = serial encoder; SB1BF‑Y160 = incremental encoder.

• Hardware: Z = special I/O/feedback; B = standard 200 V power stage.

• Firmware: D base + Y21; F base + Y160 (different OEM profiles).

• Use Case: Y21 for older serial‑encoder machines; Y160 for incremental‑encoder CNC.

Typical Applications

• Legacy CNC machines and machining centers with serial‑encoder S‑series motors.

• Special‑purpose automation: Rotary tables, material handling, custom assembly stations.

• Drop‑in replacement for original Y21‑configured VS‑800 drives.

Availability & Warranty

• Status: Original manufacturing discontinued.

• Condition: Fully tested used / refurbished.

• Warranty: 6–12 months (standard).

• Best For: Cost‑effective repair of aging production lines with Y21‑specific machines.
