What should I use here - Need changing value in different processes

Here is my new code:

use ieee.numeric_std.all;
entity StepperMotorController is
  port(
    stepper_clk_i    :in std_logic;

    Led7,Led6,Led5,Led4:out std_logic;
    LED7S : OUT STD_LOGIC_VECTOR (7 DOWNTO 0)
	);
end entity StepperMotorController;
architecture structure of StepperMotorController is

	signal counter:unsigned(2 downto 0):="000";  -- FROM 1 DOWN TO 0 > CHANGE TO 2 DOWN TO 0
	signal clk_12Hz, clk_6Hz, clk_3Hz, stepper_clk:std_logic; -- create a 3Hz clock for 1:2:3 speed

	signal count:integer range 0 to 10:=0;
	signal windings:std_logic_vector(3 downto 0);
	constant STEP1: std_logic_vector(3 downto 0):="1000"; -- for 15 degrees we need 8 steps which get repeated
