Ac Line Voltage; Overfrequency Limit - Reliance electric GV3000/SE Instruction Manual

H.021

AC Line Voltage

Parameter Range: 300 VAC - 565 VAC
Initial Setting: 380 VAC
Type: Configurable (in standby only)
Description: This parameter is the phase-to-phase nominal line voltage provided to the drive
input power terminals.
If the internal Braking Unit option is used, see also Section 2, Table 2-5, Note 1) of
Power units manual 49'1327.
NOTE: The value entered should not deviate more than +/-10% from actual line voltage.
If this parameter is set too low, it may cause a drive fault on
- overfrequency, if drive runs unstable, or
- overvoltage, if line voltage is 15% above parameter setting.
H.022
Parameter Range: 30.0 to 4 x H.001 + 5% or 210 Hz (Drive will use the lesser value)
Initial Setting: 90.0 Hz
Refer to: P.004 Maximum Speed
Type: Configurable (in standby only)
Description: This parameter provides overspeed protection by setting the fault level for maximum
frequency output. If actual frequency exceeds the set value, the inverter will fault
(OF will be displayed on the keypad/display) and the drive will stop.
The overfrequency limit should be set approximately 15 Hz above Maximum
Speed (P.004).
Slip compensation (slow response) and stability circuits (fast response) may add
values to frequency reference and increase output frequency.
Maximum Speed (P.004) should not be set above 200 Hz.
WARNING: The user is responsible for ensuring that driven machinery, all drive-
train mechanisms, and process line material are capable of safe operation at the
overfrequency limit. Failure to observe this precaution could result in bodily injury.
