S748-772 Instructions Manual | 7 Technical description
Integrated safety
Appropriate insulation and creepage distances and electrical isolation ensure safe elec-
trical separation, as per IEC 61800-5-1, between the power input / motor connections and
the signal electronics.
Soft-start, overvoltage detection, short-circuit protection, phase-failure monitoring.
Temperature monitoring of the servo amplifier and motor (if our motors and prefabricated
cables are used).
Safe stop (up to SILCL3 acc. to IEC 62061, PLe acc. to ISO13849-1), (➜ # 41)
Slot for safety card with more safety functions for the safe drive operation, (➜ # 153)
Auxiliary supply voltage 24V DC
Electrically isolated, internal fusing, from an external 24V DC power supply unit.
Separate 24V supply input for internal electronic supply
Separate 24V supply input for motor holding brake supply
Separate 24V supply input for digital outputs
Operation and parameter setting
With our user-friendly setup software DRIVEGUI.EXE, for setup via the serial interface of
a PC.
If no PC is available: direct operation by two keys on the servo amplifier and a 3-character
LED display.
Fully programmable via RS232 interface.
Read and write access to parameter records and firmware via smartcard.
Completely digital control
Digital current controller (space vector, pulse-width modulation, 62.5 μs)
Adjustable digital speed controller (62.5 μs)
Integrated position controller, with adaptation possibilities for all applications (250 μs,
optionally 125 μs)
Integrated 24V step/direction interface for connecting a servomotor to a stepper controller
Inputs and Outputs
programmable analog inputs (➜ # 99)
programmable analog inputs (➜ # 100)
2 programmable digital inputs/outputs (direction selectable) (➜ # 100)
Programmable logical combinations of digital signal
1 input Enable (➜ # 100)
2 inputs STO Enable (➜ # 101)
2 STO-Status Outputs (➜ # 102)
