Selection and Replacement Suggestions
Intra-series Replacement: Prioritize PSR30-600-81 (24V control) or PSR37-600-70 (higher margin) with the same mounting dimensions and compatible wiring.
Upgrade Replacement:

For adding current limiting function → select PSE30-600-70

For communication and torque control → select PSS30-600-70

For advanced diagnosis and display → select PSTX30-600-70

Cross-brand Replacement: Choose products with the same rated current (around 30A) and control voltage (100-240V e), and pay attention to confirming differences in mounting dimensions and wiring methods.
Key Matching Parameters: Ensure that rated current ≥ motor rated current, main circuit voltage ≥ supply voltage, and control voltage matches the control system.
