* means brake unit is optional built-in. Take 18.5G/22L for example: the model without brake unit is GK600-4T18.5G/22L, and the model with brake unit is GK600-4T18.5G/22LB. Braking resistor needs to be mounted externally with reference to Table 3-3.

** means the rated input current configured a DC reactor. The drive GK600-4T90G/110L or above is provided with an external-mounted DC reactor in shipment as default. Be sure to connect the DC reactor. Failure to comply may result in drive abnormal running.
