Read the return value
of P5.097 after
executing the macro
8-194
Create E-Cam table: rotary shear (adjustable synchronous speed zone)
This macro automatically calculates the data for the E-Cam table according to the
macro parameters and stores them in the data array specified by P5.081. After this
macro is executed, if the macro parameters have been modified, the E-Cam table
must be recreated and you must execute this macro again. Data in the E-Cam table is
changed after this macro is executed; thus, do not execute this macro when E-Cam is
in the engaged status. After this macro is executed, the E-Cam table is not stored in
EEPROM automatically.
In E-Cam applications, parameters (such as P5.083 and P5.084) that are irrelevant to
this macro are not listed here. Set the parameters according to the actual application.
Refer to Section 7.3.7 Rotary shear.
P5.081 (Start address for data array)
P5.082 (E-Cam segment number) = N (range 30 - 72)
P1.044, P1.045 (E-Gear ratio)
P5.093.H (high word)(Hex) = S (S-curve level, range 1 - 4)
P5.093.L (low word)(Hex) = W (degree of waiting zone, range -1 to 170 degrees)
Supplementary formula: W´ = 180 + 360/N – 360/R + Y/2
When P5.093.L < W´, E-Cam table is in error (failure code 0xF07A)
When P5.093.L = W´, initial speed is 0 in E-Cam table
When P5.093.L > W´, initial speed > 0 in E-Cam table, and W must be set to -1
P5.094 = Y (degree of synchronous speed zone, range 0 to 330 degrees)
P5.095.H (high word) = A (number of teeth on the motor) x C (cutting count)
P5.095.L (low word) = B (number of teeth on the cutter)
P5.096 = 1000000 x R x V (range 1.88 > R x V)
R (cutting length ratio) = L (target cutting length) / ℓ (perimeter of cutter)
V (speed compensation, range -20% to 20%) = cutting speed / feeding speed
V = 1.0: during cutting, the speed of cutter is the same as the feeding speed
V = 1.1: during cutting, the speed of cutter increases 10%
V = 0.9: during cutting, the speed of cutter decreases 10%, and so on
0xF071: the clutch is engaged, so the E-Cam table cannot be created
0xF072: P5.094 degree of synchronous speed zone exceeds the range (0 - 330)
0xF073: S-curve level of P5.093.H exceeds the range (1 - 4)
0xF074: P5.093.L degree of waiting zone exceeds the range (-1 to 170)
0xF075: data of P5.096 exceeds the range (50000 - 5000000)
0xF076: P5.082 E-Cam segment number exceeds the range (30 - 72)
0xF077: P5.081 start address for data array exceeds the array length
0xF078: E-Gear ratio set by P1.044 and P1.045 is too high. Decrease the value of
P1.044 and P1.045 but maintain the same proportions. For example: adjust
167772160 : 1000000 to 16777216 : 100000
0xF079: degree of acceleration zone is too small. Decrease the value for the waiting
zone, synchronous speed zone, or S-curve level.
0xF07A: waiting zone < minimum waiting zone. Increase the value for the waiting
zone or decrease the value for the synchronous speed zone.
