5.2 Important parameters on the SIMODRIVE 611U
Description
This table lists the parameters of the SIMODRIVE 611U that are evaluated in connection
with the technology CPU or must be taken into account during adaptation to the technology
CPU.
Some of the listed parameters are supplied during the standard commissioning (see the
"Commissioning" section). Some of the parameters can also be entered using the
configuration screen forms.
Drive parameters can also be written via the user program. For further information, refer to
the "S7 Technology" Manual, "Technology functions - basic functions, FB 454
MC_WriteRecord - write data record" section.
Table 5-1 Important parameters and their meaning
Parameter Meaning
P 660 Function selection for input I0.x
• 79 Zero mark substitute
If the encoder zero mark cannot be evaluated when homing, then a signal supplied from a mounted
sensor can be fed via this input as "zero mark equivalent".
• 80 Measuring input
maximum number of measuring inputs with SIMODRIVE 611U = 1; caution: Measuring can only be
performed via this input (I0.x).
P 700 Operating mode
For 2-axis module only: Axis B can be deselected.
P 875 Expected optional module type
PROFIBUS communication for Drive B can be deactivated here, if only one axis is operated on the 2-axis
module.
P 879 Sign-of-life monitoring in the drive is active
Bits 0, 1, 2: permitted sign-of-life error
Bit 8: deselect the sign-of-life monitoring
Bit 12: activate the direct measuring system
Bit 13: use incremental measuring system with zero mark equivalent
P 880 Specifies scaling of the speed for motion with PROFIBUS DP. Here you specify the maximum speed of
the motor. You must also enter this speed in S7T Config when the Axis technology object is created.
P 881 Specifies scaling of torque reduction for motion with PROFIBUS DP.
P 915 PROFIBUS process data setpoint assignment
P 916 PROFIBUS process data actual value assignment
P 918 DP slave address as specified in the STEP 7 project with HW Config.
P 922 Message frame type as specified in the Axis technology object. Also refer to the "Adapting message
frames individually" item.
P 1001 Speed ctrl clock cyc
Input value 4 → 4 x 31.25 µs = 125 µs for sin/cos 1 Vpp drives
Input value 16 → 16 x 31.25 µs = 500 µs for resolver drives
P 1042
P 1044
Fine resolution absolute track G1_XIST1 → fixed input value: 11
Fine resolution absolute track G2_XIST1 → fixed input value: 11
P 1043
P 1045
Fine resolution absolute track G1_XIST2 → fixed input value: 9
Fine resolution absolute track G2_XIST2 → fixed input value: 9
P 1795 Firmware for option module
P 1799 Firmware for closed-loop controller
