3.9 Maintenance and commissioning mode
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 axis 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 of the
programmed movement. Programming parameters for generating internal profiles are: speed,
stroke in motor revolutions, starting position and interval, in seconds, between forward and
reverse movement.
To perform a wiring test the motor must be disconnected from all loads, including inertia
loads; disable the drive via software (b40.9=0), set Pr30=0, 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. The error codes are as follows:
0
no error
1
b40.9=1 or drive not enabled via hardware
2
motor phase sequence and resolver direction incompatible
3
number of motor poles and Pr29 incompatible
4
resolver phase error
5
Pr30 set to value other than zero
99
procedure aborted
By setting various values in Pr57 you can get further useful information for installation and
maintenance (see table in block diagrams).
OPERATING MODE 8 PARAMETERS
Pr50
Manual speed
. Unit=rpm, default=100. This is the speed at which manual
movements are performed, as executed using b70.1, b70.2 with b70.0=0 and
b40.2=1.
Pr51
Profile execution speed
. Unit rpm, default=1000. Speed during execution of the
profile.
Pr52
Stroke
. Unit=revs, default=30. Distance, in motor shaft revolutions, to be completed
during profile generation.
Pr53
Starting point
. Default=1. When set to 1 at start profile (b70.0) the motor will start
spinning and perform Pr52 revolutions in a positive direction. if set to 2 the motor
will start moving and perform Pr52 / 2 revolutions in a positive direction. If set to 3,
the motor will start moving and perform Pr52 revolutions in a negative direction.
Pr54
Delay
. Unit=0.1 secs, default=1. During profile execution, the drive pauses for an
interval Pr54 at zero rpm between positive speed movement and negative speed
movement.
Pr55
Deviation index
. During profile execution, assuming the same Pr16 value, the
optimum value of Pr17 is obtained by reducing the value Pr55 to a minimum.
Pr56
Value of requested information
. Returns the information requested by means of
Pr57.
Pr57
Requested information
. This parameter serves to request various information from
the drive. The table of available information is shown in the block diagram of
operating mode 8.
