4.2 Programming Parameters
m
CAUTION: Do not touch any circuit components while the main AC power is on. High voltages
are supplied to the inverter (including the programming switches). Wait for at least three
minutes after the supply voltage has been switched off before performing any service on the
unit. Failure to adhere to this warning can result in injury.
Before shipping the unit to you, the parameters are set at the factory, which may be different from the default
settings, to meet the performance requirements for your crane application. Changing parameters without full
understanding of the inverter functions could cause damage to the equipment or create an unsafe condition.
The TMU VFD uses dip switches to program the features. The state of each switch is either OFF (0) or ON
(1). There are five parameters that are possible to set by switches S1 through S4.
Table 7. TMU VFD Dip Switch Settings
Switch S1 = Maximum speed, upper frequency output setting
Switch S2 = Minimum speed, lower frequency output setting
Switch S3 = Acceleration / Deceleration Ramp Time
Switch S4 = Control Mode (S4-1) and Motor Parameters (S4-2-3-4)
