The FM100 variable frequency drive is partly programmable. There are more than a hundred parameters that you can set from the front panel (or from a serial line, if you want to hook up a computer). Here are the few parameters (which Teco-Westinghouse calls "functions") that we changed from the factory defaults.
| Function | Description | Setting | Notes |
| 001 | Acceleration Time | 5 sec | Shortest acceleration time that keeps the startup current under 15 amps (any more than this might trip the overcurrent breaker in the RL125, if sustained for too long). |
| 002 | Deceleration Time | 5 sec | The default 10 seconds seems very slow. Could shorten this until we really warm up the braking transistor, but 5 seconds works well enough. |
| 003 | Start/Stop from TM2 | 0001 | Remote control will simply run the dust collector in the "forward" direction, or stop it. (Many combinations of run/stop and forward/reverse are available.) |
| 005 | V/Hz Pattern | 0 | General-purpose starting torque; simple ramp up to full voltage at 50Hz. (Might want to experiment with changing this to a variable-torque setting.) |
| 010 | Start/Stop Control | 1 | Permit the remote control to start and stop the dust collector by operating a relay connected to terminals on the TM2 terminal strip. |
| 011 | Frequency Command Selection | 1 | Use the front-panel potentiometer to set the maximum frequency. |
| 044 | Stopping Mode | 0010 | Decelerate to a stop (rather than coasting), and enable braking resistor overheat protection. |
| 047 | Meter Display Mode | 0111 | Enable display of output voltage, bus voltage, and output current. |
| 069 | Electronic Overload Protection | 0100 | Motor overload protection should permit continuous running at 113% of rated current, or up to 60 seconds running at 123% of rated current. This is tailored for a "fan-type" load. |
| 070 | Motor Rated Current | 11.6 amps | The RL125 motor plate shows an 11.6A rating. |
| 077 | Overtorque Control | 0111 | Enable overtorque detection during motor operation, and coast to a stop if an overtorque condition occurs. |
| 078 | Overtorque Detection Level | 100% | Overtorque condition occurs if the output current exceeds the motor's rating. (This is pretty conservative, but it works, and it eliminates the need to disconnect the 15A overcurrent breaker in the RL125 itself.) |
