I. Spindle motor KW60 S1
(“S1-100%” indicates that the motor power is used at 100% load in continuous operation in S1 mode. S1 operation is the mode of operation in which the motor operates continuously and carries the maximum load for which it is designed. When the motor is operated at its maximum power in S1 mode, this means that it can deliver its full power continuously over a longer period of time without overheating or being damaged)
II. Spindle motor S2 KW90
(Spindle motor power in S2 operation: “S2” refers to the motor operating mode in which the motor operates periodically while simultaneously carrying a load that is higher than that in continuous operation. The spindle motor power in S2 operation indicates the maximum power that the motor can deliver under these conditions)
