7.2.3 Servo
Permanent magnet motor with speed and position feedback
Action Detail
Before power-
up
Ensure:
• Enable signal is not given (terminal 30)
• Motor thermistor is connected or terminal 8 is linked to 0V
• Run signal is not given
• Motor is connected
• Feedback device is connected (U, V, W required for incremental encoders)
The motor must be uncoupled from any gearbox or load before an autotune is carried out.
Power-up the
drive
• Change drive operating mode to servo
Set Pr xx.00 to 1253 / 1254 (USA).
Change Pr 0.48 to ‘SErUO’
Press the reset button
• Ensure the drive displays ‘inh’ (‘SEP.EC’ trip if 8V SINCOS encoder feedback is being used)
If the drive trips, see Chapter 12 Diagnostics
on page 198.

parameters
Encoder
• Encoder power supply
Pr 3.23 = 0, 5V
Pr 3.23 = 1, 15V. (If Pr 3.23 = 1 then termination resistors should be disabled - Pr 3.24 =
1)
• Encoder PPR (pulses per revolution)
Enter PPR in Pr 3.21
Resolver
• The default setting is for a transformation ratio of 0.33 (3:1), if the resolver has a
transformation ratio of 0.5 (2:1), set Pr 16.10 = 1
SINCOS
• Encoder power supply
Pr 16.15 = 0, 5V
Pr 16.15 = 1, 8V. (Save parameter and cycle power to clear ‘SEP.EC’ trip)
• Encoder PPR (pulses per revolution)
Enter PPR in Pr 16.12
Enter motor

Enter:
• Motor rated current in Pr 0.46 (A)
• Number of poles in Pr 0.42

Enter:
• Maximum speed in Pr 0.02 (rpm)

acceleration /
deceleration
rates
Enter:
• Acceleration rate in Pr 0.03 (s/1,000rpm)
• Deceleration rate in Pr 0.04 (s/1,000rpm) (If braking resistor fitted, set Pr 0.15 = FAST)
Autotune
•Set Pr 0.40 = 1, close the enable signal (terminal 30) and wait for the drive display to show
‘StOP’
If the drive trips, see Chapter 12 Diagnostics on page 198.
The motor must be uncoupled from any gearbox or load before an autotune is carried out.

Enter 1000 in Pr xx.00
Press the red reset button or toggle the reset digital input (ensure Pr xx.00 returns to 0)
