2x over-excitation
The EMP controller is a contactless controller used for electromagnetic
clutches/brakes. It uses a 2x over-excitation method and a time lag
circuit to achieve very stable operation even when high frequency
and high precision is required. Additionally, it uses a fully contactless
technique circuit configuration utilizing power transformers, yielding
high performance and long operating life. |

PS terminal is for switching CL/MB by an external power source. See the operation
manual for details. |
| 2 |
Only current of several milliamps can be used for the external signal
so ensure an appropriate input. |
