Yaskawa GPD503 Drive - Manual (Page 34)

2.2 ACCEL/DECEL TIME
A. bn-01: Accel Time 1 Factory setting (each): 10.0 seconds
bn-02: Decel Time 1
Range (each): 0.0 to 6000.0 seconds
bn-03: Accel Time 2
bn-04: Decel Time 2
The GPD 503 incorporates two sets of individually programmable acceleration and
deceleration times.
B. Sn-15 thru Sn-18: Multi- Data 07 : Accel/Decel Time Selection
function Inputs (Term. 5 thru 8)
By programming data 07 into one of the multi-
function system constants (Sn-15 thru Sn-18),
one of the multi-function input terminals (5 thru
8) becomes a time selection input. When the
input terminal (i.e. external contact) is open,
Time 1 (bn-01/bn-02) is selected. When the
input terminal is closed, Time 2 (bn-03/bn-04)
is selected.
C. Sn-19: Multi-function Analog Data 06 : Accel/Decel Time Coefficient
Input (Term. 16)
The multi-function analog input at terminal 16
may be configured to allow analog control of the
Accel/Decel time. The input voltage, in the
range of 1 to 10V, determines the coefficient by
which the Accel/Decel time is reduced:
Actual Accel/ = Accel/Decel Time
Decel Time Coefficient
EXAMPLE:
Accel/Decel Time = 10 sec *
Voltage Ref. at Term. 16 = 5V
Actual Accel/ = 10 sec = 2 sec
Decel Time 5 (coefficient)
