7 Drive Machine Data (SIMODRIVE Drive MD) 07.97
7.3.2 Drive MD (data description)
Function switch 1012
Default value Lower input limit Upper input limit Units
0000 0000 FFFF Hex
Active
at once
Input of the configuration for switch-on functionality referred to the SIMODRIVE System 611D.
Value table:
Bit 0 Ramp-up encoder follow-up 0 = not active
1 = active
Bit 1 Reserved
Bit 2 Drive ready terminal-dependent 0 = the drive is ready when no ZK1
alarm is active
1 = the drive is ready when those of
the following conditions apply
simultaneously:
– no ZK1 alarm
– terminal 63=1 (I/R module)
– terminal 64=1 (I/R module)
– terminal 663=1 (drive module)
Bit 3 Not assigned
Bit 4 ZK2 parameterization errors 0 = ZK2 parameterization errors are
not supported (default setting).
An error cause shutdown (servo
disable)
1 = ZK2 parameterization errors are
supported: An error causes a
warning to be displayed on the
screen
Bits 5-15 Not assigned
Enable motor switchover 1013
Default value Lower input limit Upper input limit Units
0 0 100 Hex
Active on
Power On
Various motor switchover variants can be enabled
The function motor switchover in the control means switchover between motor data set 1 (MD
1xxx) and 2 (2xxx).
Possible switchover variants are:
• Star/delta switchover, motor data set 1 star connection, motor data set 2 delta connection.
Switchover of the motor windings must be performed externally with contactors that are
controlled by the PLC. Synchronization with the drive is performed by the control and
status word of the cyclic interface.
• Switchover between two real motors. Motor data set 1 for motor 1, motor data set 2 for
motor 2. Motor switchover is performed externally using contactors, synchronization via
control and status words.
Note:
The machine for the 2nd motor must be parameterized in order to be able to enable the
star/delta switchover. The drive considers the 2nd motor to be parameterized if machine data
MD 2102 does not include the value 0.
