Peak Hold Current Monitoring Function
This function saves the peak value (effective value) of the Inverter output current and displays it on the
Digital Operator for monitoring (U1-83). The Inverter output frequency at the moment the peak current
value is saved can be also monitored (U1-84).
At trial operation, perform adjustments so that the Inverter output current is limited to 150% of the rated
current checking the constants U1-83 and U1-84 of this function.
■Related Status Monitoring Constants
* 1. Applicable for G7-Series Inverters with software versions PRG 1039 and later.
* 2. The minimum unit differs depending on the Inverter capacity. (0.01 A for Inverter of 0.4 kW to 7.5 kW, and 0.1 A for Inverter of 11 kW or more)
* 3. The setting unit can be selected in o1-03.
Related Fault Tracing Constants
The peak hold values are saved in the fault trace memory when a fault occurs.
* 1. Applicable for G7-Series Inverters with software versions PRG 1039 and later.
* 2. The minimum unit differs depending on the Inverter capacity. (0.01 A for Inverter of 0.4 kW to 7.5 kW, and 0.1 A for Inverter of 11 kW or more)
IMPORTANT
The values of peak current and output frequency during peak hold will be cleared when the Inverter stops and then starts,
or when the power is turned OFF and then ON. They will be retained while being baseblocked (stopped).
