A drive exists never alone but is always a part of another element such as linear movers, mover or conveyor. A drive translates outputs of the PLC into speeds or positions.
There are several kinds of drives:
| • | Bit motor |
This drive can go forward and backward on the same speed. You can either enter one or two PLC outputs. You can also select forward/backward with pulse response. In this case the drive behaves like a 5/2-way valve with pulse response.
| • | Bit motor with two speeds |
Here you can enter another bit ‘fast’ and corresponding to that another speed.
| • | 4/2-way valve (spring returned) |
Here you only have to specify a PLC output, if it is specified the drive will go forward, if not the drive will go backward.
| • | Forward/Backward - Fast/Slow |
Here direction and speed are specified by four bits.
| • | Simple frequency converter with variable speed |
| • | Servo drive for linear mover |
| • | Servo drive for joint |
| • | Absolute real drive for joint (not supported anymore, please use the servo drive) |
