### Limits
Each MAX1968 TEC driver has analog/PWM inputs for setting
Each channel has maximum value settings, for setting
output limits.
Use the `output` command to see current settings and maximum values.
Use the `output` command to see them.
| Limit | Unit | Description |
| --- | :---: | --- |
| `max_v` | Volts | Maximum voltage |
| `max_i_pos` | Amperes | Maximum positive current |
| `max_i_neg` | Amperes | Maximum negative current |
| `i_set` | Amperes | (Not a limit; Open-loop mode) |
Example: set the maximum voltage of channel 0 to 1.5 V.
```
output 0 max_v 1.5
```
Example: set the maximum negative current of channel 0 to -3 A.
Example: set the maximum negative current of channel 0 to -2 A.
```
output 0 max_i_neg 3
output 0 max_i_neg 2
```
Example: set the maximum positive current of channel 1 to 3 A.
Example: set the maximum positive current of channel 1 to 2 A.
```
output 0 max_i_pos 3
output 1 max_i_pos 2
```
