3.6.3 Maintenance and commissioning
This operating mode is designed to assist technical personnel during commissioning.
Mode 8 provides various tests to check drive wiring. It’s also possible to move the move the
shaft manually by means of Pr50, b70.1 and b70.2 or using the internal profile generator, which
simplifies speed control loop set-up and ensures that there is no overrun on the programmed
movement. Programming parameters for generating internal profiles are: speed, motor revolutions,
starting position and interval, in seconds, between forward and reverse movement.
To perform the wiring test the motor must be disconnected from all loads, including inertia loads;
disable the drive via software (b40.9=0), Pr30 must be zero, enable the drive via hardware and set
b70.3=1. The drive will now execute the test routine. When terminated (b70.3=0), the error code in
Pr56 can be displayed after setting Pr57=0.
Error codes:
0
no error
1
test not executed
2
motor phase sequence and resolver direction incompatible
3
number of motor poles and Pr29 incompatible
4
resolver phase error
5
Pr30 value not zero
99
procedure aborted
By setting the various values in Pr57 you can get other useful information for installation and
maintenance (see table in block diagrams).
PARAMETERS FOR OPERATING MODE 8
Pr50
Manual speed
. Unit=rpm, default=100. This speed value is used for manual movements
executed using b70.1 , b70.2 with b70.0=0 and b40.2=1.
Pr51
Profile execution speed
. Unit=rpm, default=1000. This is the speed at which the
trapezoidal profile is executed.
Pr52
Distance
. Unit=revolutions, default=30. This is the number of revolutions of the motor
shaft that must be performed during generation of the profile.
Pr53
Starting point
. Default=1. If set to 1, at start profile (b70.0) the motor will start rotating
and execute Pr52 revolutions with positive speed. If set to 2 the motor will start rotating
and execute Pr52 / 2 revolutions with positive speed. If you set 3 the motor will start and
execute Pr52 revolutions at negative speed.
Pr54
Pause
. Unit= tenths of a second, default=1. During execution of the profile the drive stops
between positive speed movement and negative speed movement for an interval of Pr54 at
zero rpm.
Pr55
Deviation factor
. During execution of the profile, assuming the same value of Pr16 the
optimal value of Pr17 can be achieved by minimising the value of Pr55.
Pr56
Value
. Returns information requested with Pr57.
Pr57
Information request
. This parameter serves to query the drive. A table of queries is
shown in the block diagram of operating mode 8.
