<1> The number of decimal places in the parameter value depends on the drive model and the ND/HD selection in parameter C6-01. This value has two
decimal places (0.01 A) if the drive is set for a maximum applicable motor capacity up to and including 11 kW, and one decimal place (0.1 A) if
the maximum applicable motor capacity is higher than 11 kW.
<2> When reading the value of this monitor via MEMOBUS/Modbus, a value of 8192 is equal to 100% of the drive rated output current.
<3> The display resolution depends on the ND/HD selection in parameter C6-01. This value has two decimal places (0.01 kW) if the drive is set for a
maximum applicable motor capacity up to and including 11 kW, and one decimal place (0.1 kW) if the maximum applicable motor capacity is
higher than 11 kW.
