【英文介绍】

The Allen-Bradley 20-750-UFB-1 module is the PowerFlex 750 Universal feedback option module. When using the Safety Speed Monitor option module, only the PowerFlex 755 inverter supports the 20-750-UFB-1 module (The Safety Speed monitor option must be used with the 20-750-UFB-1 module or the dual increment encoder with the directory number 20-750-DENC-1). There are two status indicators on the 20-750-UFB-1 module: Indicator 1 shows the status of the 20-750-UFB-1 module board, and indicator 2 shows the status of the DPI communication port. The DIP switch is provided ON the 20-750-UFB-1 module for configuration. When the feedback signal is connected to the main safety channel, the DIP switch is set to S1 ON, S2 OFF and S3 ON. When the feedback signal is connected to the secondary safety channel of the DIP switch, the DIP switch is set to S1 OFF, S2 ON and S3 On. When connecting the feedback signal to the primary and secondary channels of the DIP switch, the Settings will be S1 ON, S2 ON, and S3 ON. When the PowerFlex 755 inverter is used as part of an integrated motion system, the 20-750-UFB-1 module can be used in different combinations. When using 2 feedback options and I/O, the 20-750-UFB-1 module will be used for ports 4 to 6. When using 2 feedback options, 1 safe torque off option and I/O, the 20-750-UFB-1 module is available for ports 4 and 5. When using 2 feedback options, 1 safe speed monitoring option and I/O, the 20-750-UFB-1 module is available for ports 4 and 5.

The 20-750-UFB-1 is Allen-Bradley's universal feedback encoder module. This module is an accessory module that is compatible with PowerFlex 755 inverter and has a Safety speed monitor option module installed. The module can be installed with Allen-Bradley PowerFlex 755, PowerFlex 755TL and PowerFlex 755TR adjustable frequency AC drives.

The 20-750-UFB-1 comes with one (1) input, supports differential or single-ended operation, constant current absorption operation, and is rated at approximately 10 mA. It has a minimum operating voltage of 3.5 volts DC, a maximum DC voltage of 7.5 volts, and a source current of 10 mA. To connect this module to an input source, an acceptable cable length does not exceed 30 meters or 100 feet @ 5 volts DC. In addition, the maximum input frequency of the input signal must not exceed 250 kilohertz.

Encoders supported by the module include Heidenhain (EnDat) with a supply voltage of 5 V and 250 MA; High resolution signal of sine/cosine 1V P-P; Maximum cable length 100 m (328.1 ft); The update rate is 102.4 μs and the maximum input frequency is 163.8 KiloHertz. SSI encoders, Stegmann (Hiperface), BiSS, Stahl (linear) and Temposonics (linear) encoders are also supported.

The 20-750-UFB-1 is equipped with three (3) sets of DIP switches for safe channel selection. To set the primary safe channel, set the S1 slider to ON; The S2 slider becomes OFF and the S3 slider becomes ON. For secondary safety channels, set the S1 slider to OFF; The S2 slider changes to ON and the S3 slider changes to ON. For primary and secondary safety channels, set the S1 slider to ON; The S2 slider changes to ON and the S3 slider changes to ON.
