| Power | 5V at 250 mA max. is available to power the encoder, protected by self-resetting fuse. |
| Connection |
Female 26 way high density D-Sub. Encoder connects via adapter cable according to encoder type. Adapter cables for supported encoders are available from AML. |
| Incremental encoder support |
Digital (RS422) incremental encoders having differential A, B and Z signals.
Single ended P and Q limits signals are supported.
Maximum clock rate 1 MHz. |
| Absolute encoder support | 26 bit BiSS-C (support for other bit depths may be added via firmware update) |
| Motor temperature measurement | |
| Type | Selectable PT100 RTD or K-Type thermocouple |
| Range | -200°C to 240°C |
| Accuracy | ±15 °C for thermocouple, ±5 % for RTD |
| Fault detection | RTD: Open and short-circuit Thermocouple: Open circuit only |
| Operating modes | |
| • Remote – Control and configure via USB, Ethernet or Serial • Step, Direction Enable (SDE) – For connection to an external motion controller or PLC • Bake – Programmed cycle to heat the motor while stopped to drive off adsorbed gasses |
