S7-200 Programmable Controller System Manual
Setting Up the MM4 Drive
Before you connect a drive to the S7-200, you must ensure that the drive has the following system
parameters. Use the keypad on the drive to set the parameters:
1. Reset the drive to factory settings (optional):
If you skip this step, ensure that the following parameters are set to these values:
USS PZD length:
USS PKW length:
2. Enable the read/write access to all parameters (Expert mode):
3. Check motor settings for your drive:
The settings will vary according to the motor(s) being used.
In order to set the parameters P304, P305, P307, P310, and P311, you must first set
parameter P010 to 1 (quick commissioning mode). When you are finished setting the
parameters, set parameter P010 to 0. Parameters P304, P305, P307, P310, and P311 can
only be changed in the quick commissioning mode.
4. Set the local/remote control mode:
5. Set selection of frequency setpoint to USS on COM Link:
6. Ramp up time (optional):
This is the time in seconds that it takes the motor to accelerate to maximum frequency.
7. Ramp down time (optional):
This is the time in seconds that it takes the motor to decelerate to a complete stop.
8. Set the serial link reference frequency:
9. Set the USS normalization:
10. Set the baud rate of the RS--485 serial interface:
11. Enter the Slave address:
Each drive (a maximum of 31) can be operated over the bus.
12. Set the serial link timeout:
This is the maximum permissible period between two incoming data telegrams. This feature
is used to turn off the inverter in the event of a communications failure. Timing starts after a
valid data telegram has been received. If a further data telegram is not received within the
specified time period, the inverter will trip and display fault code F0070. Setting the value to
zero switches off the control. Use Table 11-1 to calculate the time between the status polls
to the drive.
13. Transfer the data from RAM to EEPROM:
P0971=1 (Start transfer) Save the changes to the parameter settings to EEPROM
