The control connector pinouts (CN1) are mapped differently, and the encoder connector (CN2) requires a newer serialization interface.

When installing multiple units adjacent to each other, a minimum horizontal spacing of 10 mm and vertical spacing of 40 mm is required to prevent cumulative heat buildup. If high-inertia cycling is required, monitor parameter PC02 (regenerative load ratio) during commissioning. If the ratio exceeds 100%, the internal regenerative resistor is saturated, and an external regenerative option (such as the MR-RB32 module) must be added to prevent \"AL.30\" (regenerative overvoltage) faults.\u003c\/p\u003e\n\n\u003ch3\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eTo avoid control loop instabilities, command pulse input lines (terminals connected to CN1) must utilize high-quality, individually twisted-pair shielded cables. Ground the overall cable shield to the connector shell on the amplifier side only. When commissioning, verify that the single-phase control power inputs (L11\/L21) are energized prior to or simultaneously with the primary three-phase main power (L1\/L2\/L3); a timing delay in control loop initialization can lead to a transient \"AL.E9\" (main circuit off) alarm state.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 1rem; margin-bottom: 1.5rem; border-radius: 4px;\"\u003e\n  \u003cp style=\"margin: 0; font-weight: bold; color: #9b2c2c;\"\u003eCRITICAL WARNING:\u003c\/p\u003e\n  \u003cp style=\"margin: 0.5rem 0 0 0; color: #9b2c2c; font-size: 0.95rem;\"\u003eEnsure all primary 3-phase AC power lines (L1\/L2\/L3) and control power lines (L11\/L21) are fully disconnected and locked out.
