Table 3-16 Trolley VFD Variable Parameter Setup Procedure


Each dual speed trolley model has a range of available speeds/frequencies (upper and lower
limits) and acceleration/deceleration time parameters.

The VFD deceleration/acceleration time within the frequency range (0 to 120 Hz) is actually used
by setting the deceleration/accelation time at 120 Hz.

Example: the default setting for the RY030 trolley is set to 5.0 seconds for the accleration time of
0 to120 Hz, and 5.0 seconds fo rthe deceleration time, reference
Table 3-14 . During high speed
operation, this becomes about 60 Hz, half of 120 Hz; therefore, decleration/accceleration time is
2.5 seconds each.

Any value outside the range listed in Table 3-13 for your specific trolley is strictly prohibited.

Speeds must be set such as Low [d1-01] and High [d1-02].

After parameters are changed, a “no load” operational check must be performed.
