DBK- Resistor and overload with N.C. contact, DBKC resistor and overload with form C contact.
Table 4.2c Specifications of external 460V inverter braking resistor.
21
Crane Commander 460V series with built in dynamic brake option (1/2-10HP units require additional external resistor
for all heavy duty applications and any CMAA class 'D' uses.) (Internal D.B. resistor must be disconnected when
connecting external resistor) Units above 10HP require an external dynamic brake module in addition to resistor kit
for all applications..
A thermal overload is supplied with each resistor and is supplied loose for customer's panel mounting.
A 3 phase line disconnect contactor on input side of Crane Commander is to be opened if thermal overload trips. ie.
VFD input contactor or mainline.
Consult Drivecon for 3 pole contactor prices and ratings.
Resistors are sized for 100% braking torque for a maximum of 10% duty cycle. Suitable for hoist (with load brake)
duty, all CMAA classes A-D and traverse on CMAA Class D duty.
Consult factory for higher brake torque or cycle rates.
Note: External DB resistor supplied with Crane Commander must be disconnected and/or removed when adding
separate external DB resistor.
