Catalog excerpts

VARAN Stepper Module Enable Input The VST 012 is a VARAN module designed for the control of a stepper motor up to a maximum 10 A RMS. The available operating modes are full step, half step and micro step. The maximum sw'tching frequency of the output stage is 50 kHz. The motor output is released through the Enable input. An incremental encoder input is available for position control of the stepper motor. The module also provides four digital inputs and four digital outputs. The VARAN Out port allows the configuration of the VARAN bus in a linear structure. Number of inputs Input voltage Signal level Switching threshold Input current Input delay Status display typically +9.5 V typically 5 mA at +24 V typically 5 ms LEDs grun Digital Inputs Number of inputs Input voltage Signal level Switching threshold Input current Input delay Status display Digital Outputs typically +9.5 V typically 5 mA at +24 V typically 10 pis LEDs grun 1x VARAN Out (RJ45) (maximum length: 100 m) Incremental Encoder Input Stepper Motor Output Output current over the environmental maximum 10 A RMS continuous current at 45 °C temperature maximum 8.6 A RMS continuous current at 50 °C maximum 6.3 A RMS continuous current at 55 °C maximum 5 A RMS continuous current at 60 °C MOTION CONTROL SYSTEM
