4.6.4. 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 b40.9=1 or drive disabled via hardware
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.
