RoHS-Compliant Brake Pack bAdditional Informationb Technical reference ➜ Page F-1 Safety standards ➜ Page G-2 The SB50W provides instantaneous stop, bi-directional operation, electromagnetic brake control and thermal protector open detection functions integrated into one unit. This brake pack can sense when the thermal protector is opened, further ensuring the safety of your equipment. For greater convenience, a function has been added to reset alarms using an external signal. b List of safety standard approved products (Model, Standards, File No., Certification Body) ➜ Page G-10 ˾Features...

˾Characteristics of Brake Pack The brake pack provides stable braking characteristics for the instantaneous stop of the motor. The braking characteristics are illustrated by the braking curve, which indicates the amount of overrun corresponding to the load inertia. The braking time is 4n/f seconds or less. Where, n: overrun, f : power supply frequency. bExample of Braking Characteristics with Brake Pack Brake Pack: SB50W Motor: 4IK25GN-CW2E 2.0 Permissible Load Inertia Induction Motors For example, if the 4IK25GN-CW2E (single-phase 220/230 VAC, 25 W) and SB50W are used together to stop a...

ȣ ALARM Output (Thermal Protector Open Detection) Since the SB50W ALARM output function detects the action of the thermal protector, the current flowing in the motor is monitored. ALARM output is activated under the following conditions: •When the thermal protector built-in to the motor is activated (open) •When there is improper connection/disconnection of the power supply cable and motor cable •When the input signal is turned "ON" before the AC power supply is turned on •When the AC power supply is turned off while the motor is in operation or while it is stopped In the above conditions,...
