Application Notes
Environnement d'installation

Température de fonctionnement: 0~40°C (non‑condensing)

Storage temperature: -20~60°C

Humidité: 20~85%RH (non‑condensing)

Avoid dust, corrosive gas, and strong vibration

Operation Limits

Load torque must not exceed rated torque during continuous operation

Peak torque only usable for 3 seconds to prevent overheating

Speed must not exceed 3000 rpm to avoid mechanical damage

Entretien

Regularly check encoder and power connections for looseness

Brake life: approx. 5 millions d'opérations; inspect braking performance periodically

Keep motor surface clean for good heat dissipation

Sécurité

Motor must be reliably grounded to prevent electric leakage

Wait at least 5 minutes after power‑off before wiring

Install overload protection to prevent motor burnout

Compatible Drives

Recommandé: R88D‑KT series pulse input type driver

Or R88D‑KN series EtherCAT communication type driverDriver output must match 200W motor; recommended models: R88D‑KT02H or R88D‑KN02H
