Operating Instructions, 04/2019, A5E36037884-007
Description
Implements accurate positioning through two pulse train
input channels: 5 V differential or 24 V single end signal. In
addition, it supports the S-curve position smoothing function
Optimized PTI control mode to achieve a better dynamic
response performance
Implements accurate positioning through internal position
commands (up to eight groups) and allows to specify the
acceleration/speed for positioning
Flexibly controls motor speed and direction through external
analog speed commands (0 - ±10 VDC) or internal speed
commands (up to seven groups)
Flexibly controls motor output torque through external ana-
log torque commands (0 - ±10 VDC) or internal torque
commands. In addition, it supports speed limit function to
prevent overspeed when a motor has no loads
Supports flexible switches among position control mode,
speed control mode, and torque control mode
Allows to implement motion control tasks immediately after
the servo system with an absolute encoder is powered on,
needless of carrying out referencing or zero position opera-
tion beforehand
Switches between gains during motor rotation or stop with
an external signal or internal parameters to reduce noise
and positioning time, or improve the operation stability of a
servo system
Switches from PI control to P control with an external signal
or internal parameters to suppress overshooting during
acceleration or deceleration (for speed control mode) or to
suppress undershooting during positioning and reduce the
settling time (for position control mode)
Safely disconnects torque-generating motor power supply
to prevent an unintentional motor restart
Stops motor and clamps the motor shaft when motor speed
setpoint is below a parameterized threshold level
Supports the communication between the SINAMICS V90
servo drive and PLC with the standard Modbus communica-
tion protocol
Estimates the machine characteristic and sets the closed
loop control parameters (position loop gain, speed loop
gain, speed integral compensation, filter if necessary, etc.)
without any user intervention
Estimates the machine characteristic and sets the closed
loop control parameters (position loop gain, speed loop
gain, speed integral compensation, filter if necessary, etc.)
