Table 9 Varistor (VR) Capacity
· The brake delay time of the normal braking action is different from that of the fast braking
action. Table 1 on page 6 shows the delay time. Use a circuit that meets your requirements.
· 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.
· Use fast braking action for lifting devices or for better stopping accuracy.
· Use fast braking action when a leading capacitor is used.
·
For 15W–90W single-phase capacitor run type motor
, connect the accessory capacitor,
(see Table 7 on page 23 for the capacitor.)
· Pay attention to the following items
when driving an inverter
.
· For the inverter-driven motor with a brake, use the primary-side power
supply for braking as shown in Fig.31, and synchronize the braking
operation with the ON/OFF operation of the unit.
· For the inverter-driven motor with a brake, interlocking with the inverter
is necessary to engage/release the MC. Refer to the inverter
maintenance manual or guide.
· During the low speed running, the mechanical life might be in danger of
being shortened by reducing the cooling ability.
· When it happens, please reduce the time that brake's power is on.
