Optimize the drive.

Introduction
In the operational area Commissioning > Optimization/Test you have the option to optimize
the drives. The following functions are available:
• Current controller
• Speed controller
• Position controller
• Function generator
• Circularity test
• Servo trace
This chapter provides instructions on parameterization.
Speed adjustment
• Spindle drive:
p500 = 102, speed setpoint in p322 corresponds to setpoint 4000 0000hex
• Feed drive:
p500 = 101, speed setpoint in p311 corresponds to setpoint 4000 0000hex
The speed setpoint can be diagnosed in the corresponding drive in r2050[1+2] or r2060[1].
Speed controller settings
If standard optimization produced drive oscillation:
• Using parameter p1460, reduce p gain in the speed controller and
• Save module-specific: set p971 = 1.
Brake behavior AUS3
Depending on the requirements, the brake behavior for each drive can be adjusted to the
signal 2.AUS3. Default setting: p1135 = 0, brake with maximum current.
Parameters p1135, p1136, p1137 can be used to set a flatter braking ramp for drive-specific
parameterization.
Maximum braking ramp setting: 600 secs
