Appropriate insulation/creepage distances and electrical isolation ensure safe electri-
cal 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 prefabri-
cated cables are used).
Safe stop (SIL CL3 according to IEC 62061, PLe according to ISO 13849-1) ð p. 37.
Slot for optionalsafety card with more safety functions for the safe drive operation,
ð p. 150
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
With our user-friendly setup software DRIVEGUI.EXE, for setup via the serial inter-
face 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/write access to parameter records and firmware via memory card.
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 125µs)
Integrated 24V step/direction interface for connecting a servomotor to a stepper con-
troller
2 programmable analog inputs ð p. 95
