●
Use fast braking action for lifting devices or for better stopping accuracy.
●
DC braking capacity (for DC coil loading) exceeding 5 times the braking current shown on the name plate is recommended
for the fast braking action.
・Refer to page 6 table 1-2 for brake type.
・This drawing shows for a motor based on standard specification for domestic market. Motor
based on overseas standard shall be referred to us.
