Drive Setup & Programming
3 Drive Setup and Programming
Most drive parameters (including those required for serial communications) are not accessible through the
FLN. They can only be accessed by entering the Programming Mode of the drive itself. Refer to the MCH
Installation and Operation Manual (MH01) for more information.
When in Programming Mode, the drive will not accept any write, memorize or characterize LAO commands
from the FLN. This is necessary to prevent conflicts between the two modes of parameter modification.
The parameter information in the MCH Installation and Operation Manual is based on Lenze-AC Tech’s
standard MCH Series Modbus
TM Drive. There are some differences between the drive programming
parameters described in the manual and those that exist in the MCH Series P1 Drive.
3.1 Added Programming Parameters
59 SERIAL BAUDRATE As stated previously the communications rate is typically 4800 bps but, on some
FLN devices, it may also be 9600 bps. This parameter, which has selections
of 4800 bps (default) and 9600 bps, has been added to accommodate both
possibilities.
60 SERIAL TIMEOUT This parameter makes the serial watchdog timeout period selectable and is
described in detail in Section 3.4 Serial Communications Setup.
3.2 Omitted Parameters and Selections
36 SLEEP THRESHOLD Sleep Mode functionality has not been added to the MCH Series P1 Drive so
these drive parameters do not exist.
37 SLEEP DELAY
38 SLEEP BANDWIDTH
41 ANALOG INPUT FILTER
52 TB14 OUT The following options have not been added to these parameters in the MCH
Series P1 drive:
53 TB15 OUT
54 RELAY
INV MIN/MAX A
MIN ALARM
INV MIN ALARM
MAX ALARM
INV MAX ALARM
56 SERIAL LOSS This parameter has not been added to the MCH Series P1 Drive. For a detailed
explanation of the action that is taken when serial communications with the
FLN are lost, refer to the description of Drive Parameter #60 (Serial Timeout)
in Section 3.4 Serial Communications Setup.
