If the output torque at low speed is a problem (i.e., a heavy load is connected at low speed), set the
parameter L8-18 to 1 and the parameter L8-19 to 0.
Note 1. Do not set both parameters (L8-17 and L8-19) to 0, otherwise the Inverter may be damaged.
In that case, use a higher rank Inverter with parameter L8-17 set to 0 and parameter L8-19 set
to 1.
Note 2. Use a higher rank Inverter or set parameter C6-01 (Carrier Freq Max) to 2 kHz if a high load is
continuously connected at low speed in flux vector control mode.

In operation mode, the frequency reference, output frequency, output current, and output voltage can
be monitored immediately if the default settings are being used. One of these four values, the output
voltage, can be changed to a different value. When you want to monitor a value other than the output
voltage, set that value’s number in parameter o1-01.

Use the last two digits from the “U1 Monitor” list (U1-

table listing all of these U1 settings.
