§ DC Injection Braking at Start (n064, n066)
Restarts a coasting motor after stopping it. Set the DC Injection Braking time at start in constant n066 in units of 0.1
second. When constant n066 is set to 0, DC Injection Braking is not performed and acceleration starts from the
minimum output frequency.
Set DC Injection Braking current in constant n064 in units of 1%. The Inverter rated current is 100%.

6.3.14 Using Frequency Meter of Ammeter (n048)
Selects to output either output frequency or output current to analog output Terminals AM-AC for monitoring.
Setting Analog Monitor Output Item
0 Output frequency (10 V/maximum frequency)
1 Output current (10 V/Inverter rated current)
2 Output power (10 V/Inverter rated voltage)
3
DC bus voltage [10 V/400 V (200 V class), 10 V/800 V (400 V class)]
6.3.15 Calibrating Frequency Meter of Ammeter (n049)
Used to adjust analog output again.
Set the analog output voltage at 100% of output frequency.
