8.3 Specifications of PWM 8 Base Unit

Power supply PWM 8:

• at DC-IN socket:

Power supply: 10 - 30 V

Current consumption of PWM 8

without encoder: approx. 230 mA (5.5 W) with 24 V

power-on current approx. 1 A

Current consumption with power supply unit: approx. 15 W

• at OUT flange socket of the interface board:

Power supply: 3 - 10 V (11µApp, 1Vpp, TTL)

10 - 30 V (HTL)

Current consumption of PWM 8

without encoder: approx. 1.0 A (5 W) with 5 V

Power supply of the encoder by PWM 8:

Note: Parameter P2: U-MSYS EXTERN set to FLOATING

Encoder voltage (11µApp,

1Vpp, TTL) 3 - 9 V selectable

standard setting: 5 V ± 0´.1 V
