SIMOVERT MASTERDRIVES
Checking the sensor board:
MASTERDRIVES MC automatically detects an installed sensor board.
You can check in display parameter r826 whether the correct sensor
board is installed (see parameter list). The sensor boards have the
following codes:
♦
111 = SBP
(suitable for ROD431 etc.)
♦
112 = SBM
(suitable for ERN1397, ECN1313, EQN1325, SSI
encoders from Siemens, Fraba, TWK, TR,
Stegmann, linear scale LC181 etc. The ASIC chip
on the SBM should have firmware version V1.3 or
higher.)
♦
113 = SBM2
(same as SBM with additional analog fine resolution
on the board)
♦
114 = SBR1
(for resolver, without pulse encoder simulation)
♦
115 = SBR2
(for resolver, with pulse encoder simulation)
Check the switches and hardware parameters on sensor boards SBx if
special encoders or third-party motors are used, as described in the
"Encoder evaluation" sections in "Brief description of the technology
functions" and in the hardware instruction manual for the SBx board.

Defining the actual speed value normalization
Commissioning step:
Set the actual speed value normalization with P353:
First, set the actual speed normalization in parameter P353 [20] as
follows:
♦
Define the maximum velocity (limit velocity), tolerated by the
mechanical system of your machine, which must not be exceeded
under any circumstances.
♦
In P353 enter the speed in [min
-1
] at which the motor encoder
rotates at this maximum velocity (allowing for transmission ratios,
spindle pitches, etc.). Before entering the value in P353 you must
change to the "drive settings" parameter menu with P60 = 5. You
must exit this menu with P60 = 1 when the input is complete.
♦
If you use an external machine encoder for position sensing, enter in
P355 the speed in [min
-1
] at which the external encoder rotates at
the maximum velocity.
